Table 1-Data for bcc Fe-Ni alloys experiments

We investigated the magnetism of body centered cubic (bcc) FeNi alloys (Fe92Ni08, Fe87Ni13, and Fe84Ni16) as a function of pressure at room temperature through the bcc to hexagonal closed packed (hcp) phase transition. In each case, the fully saturated magnetic remanence attained maxima at the hysteretic bcchcp and hcpbcc transition boundaries upon compression and decompression. Magnetization maxima generally shifted to lower pressures with increasing Ni concentration.本研究于室温条件下，针对体心立方（body centered cubic, bcc）结构的FeNi合金（包含Fe₉₂Ni₀₈、Fe₈₇Ni₁₃与Fe₈₄Ni₁₆三种组分），探究了其磁性随压力的变化规律，研究覆盖了该体系从bcc至密排六方（hexagonal closed packed, hcp）的结构相变过程。在所有受试组分中，完全饱和的剩余磁化强度（magnetic remanence）均在加压时的磁滞bcc→hcp相变边界，以及减压时的磁滞hcp→bcc相变边界处达到峰值。总体而言，随着镍浓度的提升，磁化强度峰值对应的压力值逐渐降低。
