Co2CrIn: A further magnetic Heusler compound

subject

description

Summary and Outlook In summary, this work presents the synthesis andcharacterisation of the Heusler compound Co 2 CrIn.The compound is L2 1 ordered and shows no major an-tisite disorder. Co 2 CrIn turns out to be a ferrimagnetwith a magnetic moment of 1.18 µ B at 5 K. In addi-tion, the hysterisis curve reveals a soft magnetic be-haviour. A measurement of the site specific magneticmomentsis highlydesirableas it might leadto a deeperunderstanding of the magnetic properties of Co 2 CrIn.Furthermore, the measured magnetic moment is not aninteger number, as expected for a half-metallic ferro-magnet. Thus, Co 2 CrIn can not be a half-metallic fer-romagnet, as most of the other Co 2 YZ Heusler com-pounds. Acknowledgements This work is funded by the DFG (FG 559/ TP1). The au-thors thank Dr. M.
