Abstract

Mn_1.5X_0.5Sn (X = Cr, Mn, Fe, Co) nanomaterials in the hexagonal Ni₂In-type crystal structure have been prepared using arc-melting and melt spinning. All the rapidly quenched Mn_1.5X_0.5Sn alloys show moderate saturation magnetizations with the highest value of 458 emu/cm³ for Mn_1.5Fe_0.5Sn, but their Curie temperatures are less than 300 K. All samples except the Cr containing one show spin-glass-like behavior at low temperature. The magnetic anisotropy constants calculated from the high-field magnetization curves at 100 K are on the order of 1 Merg/cm³. The vacuum annealing of the ribbons at 550°C significantly improved their magnetic properties with the Curie temperature increasing from 206 K to 273 K for Mn_1.5Fe_0.5Sn.
