Magnetic properties of co and ni doped sno2 based diluted magnetic semiconductors

Abstract

Diluted magnetic semiconductors have evolved as a fascinating area of research for potential spintronics applications at practical temperature The generic problem of resistance mismatch at metal semiconductor interfaces hinders the effective spin injection therefore much attention is being focused on the development of room temperature ferromagnetic semiconductors If successful we could have new generation devices having miniaturation high energy efficiency non volatile memory large Zeema
