Abstract

öDilute magnetic semiconductors/insulators (DMS/DMI), which show ferromagnetism at room temperature, are very attractive for studying the basic mechanism of dilute magnetism and the potential application to spin transfer electronics, that is, spintronics. The chapter focuses on Fe-doped SnO2 powders prepared by the sol-gel method, SnO2 films implanted with Fe ions, and the effect of dilution and clustering of Fe ions doped into SnO2 and TiO2 by nuclear inelastic scattering using synchrotron radiation. It talks about X-ray diffraction and extended X-ray absorption fine structures (EXAFS) analysis. Temperature dependence of magnetic properties with zero field cooling (ZFC) and field cooling (FC) modes was measured by a superconducting quantum interference device (SQUID) magnetometer. The chapter discusses Mössbauer analysis of yttrium aluminum garnets (YAG) doped with dilute iron and describes microdischarge treatment of iron-doped YAG.
