Superconductivity of Materials (student preso)

Superconductivity of Materials Napat, Peerada, Chaloempol

Type l superconductors
Including thirty pure metals
Zero resistivity below a critical temperature
Characterized as soft superconductors
Has the ability to exclude
magnetic field from its interior in superconducting state :The Meissner Effect

The Meissner Effect
Become perfect diamagnet: repelled by magnetic field

Type II Conductor
Material: metal alloys, complex oxide ceramic
higher critical fields and therefore could carry much higher current densities while remaining in the superconducting state

Critical Magnetic field
Mixed superconducting (vortex state)
Normal state
Superconducting state

Niobium-Titanium Superconductor
a critical temperature of 10 K and a critical magnetic field of 15 Tesla .
fine filaments are advantageous because current flows only within a skin - depth of the surface of a superconductor

Task
Napat: Type I conductor
Peerada: Type II conductor
Chaloempol: Introduction
