This document contains a table of contents for a paper on spintronics. The table of contents shows that the paper will define spintronics and discuss the concept including electron charge distribution, photon theory, electron spin theory, and the Zeeman effect. It will also cover quantum tunneling, wave-particle duality, research areas on spintronics, requirements, spin materials like ferromagnetic and half-magnetic semiconductors, devices including giant magnetoresistance and magnetic tunnel junctions, applications such as MRAM, spin FET, spin LED and GMR sensors, advantages, disadvantages, and conclusions.
