Origin of spin reorientation transitions in antiferromagnetic MnPt-based alloys

P. -H. Chang, I. A. Zhuravlev, K. D. Belashchenko

Antiferromagnetic MnPt exhibits a spin reorientation transition (SRT) as a function of temperature, and off-stoichiometric Mn-Pt alloys also display SRTs as a function of concentra…
