Emergence of net magnetization by magnetic-field-biased diffusion in antiferromagnetic L1${}_0$ NiMn

Nicolas Josten, Olga Miroshkina, Sakia Noorzayee +6

NiMn is a collinear antiferromagnet with high magneto crystalline anisotropy ($K_2=-9.7\times 10^5{\text{J m}}^{-3}$). Through magnetic annealing of NiMn with excess Ni, strongly pi…
