Exchange bias (EB) in a single magnetic film has always been an intriguing subject to the researchers. But the quest for the origin of EB in Fe3O4 films at temperatures, T<200K is still contemplated. We report a thickness dependent observation of exchange bias at T<200K, with diminishing EB for higher thickness of oriented (111) Fe3O4 on (100) GaAs. Non-zero EB is observed to be retained even...
Detailed ab-initio studies on electronic structure and optical properties have been carried out for orthovanadates, and periodate compounds, ScVO4, YVO4, LuVO4, and NaIO4, KIO4, RbIO4, CsIO4 based on the Full potential linearized augmented plane wave method within the frame work of Density Functional Theory using Tran and Blaha modified Becke–Johnson potential (TB-mBJ). We have compared the optical...
