L1 0 CrPt phase formation and magnetic properties

Abstract

L1 0-ordered antiferromagnetic CrPt is of interest as a pinning material in exchange-biased system due to its many intriguing properties and such alloy with a (001) texture has also been used to serve as an underlayer to promote the L1 0 phase formation of other materials. Therefore, it is important to control not only the L1 0 phase formation of such material but also the texture of its ordered phase. A systematic study of the L1 0 phase formation of CrPt thin film was performed. The anisotropy of CrPt L1 0 phase has also been investigated both experimentally using CrPt/Fe bilayer system and theoretically using first principle calculation. The experimental result is in consistent with the theoretical estimation within the present thin film limitation. © 2012 American Institute of Physics.
