Abstract
A novel ferromagnetic phase of manganese-bismuth alloy has an NiAs-type unit cell structure, similar to that of Low Temperature Phase manganese-bismuth, but with manganese atoms populating interstitial sites. The novel phase, termed β-MnBi, possesses maximum magnetic coercivity at unusually high temperature. A method for forming β-MnBi includes annealing MnBi nanoparticles, for example by hot compaction, at temperature lower than 175° C.
