Spintronics is an emerging field that uses electron spin rather than charge to carry information. It promises devices with enhanced functionality, higher speeds, and lower power consumption compared to traditional electronics. Spintronic devices work by manipulating the spin states of electrons and exploiting the spin properties of ferromagnetic materials. Potential applications include magnetic RAM, magnetic sensors, and spin transistors. Spintronics may enable smaller, more energy efficient devices and overcome limitations of Moore's Law.
Spintronics is a NANO technology which deals with spin dependent properties of an electron instead of charge dependent properties.
One of the main advantage of spintronics over electronics is the magnets tend to stay magnetize which is sparking in the industry an interest for replacing computer’s semiconductor based components with magnetic ones, starting with the RAM.
With an all-magnetic RAM, it is now possible to have a computer that retains all the information put into it. Most importantly, there will be no ‘boot-up’ waiting period when power is turned on.
Another promising feature of spintronics is that it doesn’t require the use of unique and specialized semiconductor, there by allowing it to work with common metals like Cu, Al, Ag.
Spintronics will use less power than conventional electronics, because the energy needed to change spin is a minute fraction of what is needed to push charge around.
Conventional electronic devices ignore the spin property and rely strictly on the transport of the electrical charge of electrons.
Adding the spin degree of freedom provides new effects, new capabilities and new functionalities.

In our conventional electronic devices we use semi conducting materials for logical operation and magnetic materials for storage, but spintronics uses magnetic materials for both purposes. These spintronic devices are more versatile and faster than the present one. One such device is Spin Valve Transistors (SVT).
Spin valve transistor is different from conventional transistor. In this for conduction we use spin polarization of electrons. Only electrons with correct spin polarization can travel successfully through the device. These transistors are used in data storage, signal processing, automation and robotics with less power consumption and results in less heat. This also finds its application in Quantum computing, in which we use Qubits instead of bits.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

9. What is Spintronics? Spintronics is a blend of electronics with spin. It refers to the study of the role played by the electron spin in solid state physics and possible devices that specifically exploits spin properties of electrons instead of it’s charge. It promises new logic devices which enhances functionality, high speed and reduced power consumption.
10. Principle Spintronics is based on the spin of electrons rather than its charge. Every electron exist in one of the two states- spin-up and spin-down, with spins either positive half or negative half. In other words, electrons can rotate either clock wise or anti-clockwise around its own axis with constant frequency. The two possible spin states represent ‘0’ and ‘1’ in logical operations.
11. Principle Spin is a characteristic that makes an electron a tiny magnet with north and south poles. The orientation of north-south axis depends on the particle’s axis of spin. In ordinary materials, the up magnetic moments cancel the down magnetic moment so no surplus moment piles up. Ferro-magnetic materials like iron, cobalt and nickel is needed for designing of spin electronic devices.
12. Principle These have tiny regions called domains in which an excess of electrons have spins with axis pointing either up or down. The domains are randomly scattered and evenly divided between majority-up and majority-down. But, an externally applied magnetic field will line up the domains in the direction of the field. This results in a permanent magnet.
13.
14. Principle When a pool of spin-polarized electrons is put in a magnetic field, precession occurs. The frequency and direction of rotation depends on the strength of magnetic field and characteristics of the material. Thus, if a voltage pushes an electron out of gallium arsenide into zinc selenide, the electron precession characteristics change. However, if a higher voltage pushes the electron sharply into zinc selenide, the electron precession characteristics don’t change.

17. Finding the novel ways of both generation and utilization of spin polarized current. The later one is a effective method.
18. Working All spintronic devices acts according to the simple scheme: The information is stored (written) into spins as a particular spin orientation (up or down). The spins, being attached to mobile electrons, carry information along a wire and the information is read at a terminal. Spin orientation of conduction electrons survives for relatively long time (nanoseconds, compared to tens of femtoseconds during which electron moment decays) which makes spintronic device useful for memory storage and magnetic sensor applications.
19. Working These are used for quantum computing where electron spin will represent a bit (called ‘qubit’) of information. When electron spins are alligned, this creates a large scale net magnetic moment. The basic GMR device is a 3 layer sandwich of magnetic metal (such as cobalt) with a non-magnetic metal filling (such as silver). A current passes through the layers consisting of spin up and spin down electrons.
20. The electrons oriented in the same direction as the electron spin in the magnetic layer pass through quite easily while those oriented in the opposite direction are scattered. If orientation of one of the magnetic layers is changed by the presence of a magnetic field, the device will act as a filter or a spin valve letting through more electrons when spin orientation in the two layers are the same and fewer electrons when spin orientation are oppositely alligned.
