摘要:
Initial susceptibility and thermoremanent magnetization measurements have been made on atomically disordered and weakly ordered Ni3Mn. The blocking of superparamagnetic clusters yields a peak in initial susceptibility near 110 K. Ferromagnetic clusters with Curie temperatures near 265 K cause a break in the susceptibility vs. temperature curves at 265 K. Exchange anisotropy effects appear below 35 K.
