摘要: 在0.000 1~2.4 GPa流体静压力范围选30~36个压力点详细测量出FeCoNiSiVB、FeSiB、FeCrSiB和FeCoSiB四种非晶合金磁化曲线和磁导率曲线的压力效应，并采用多项式精确拟合和计算机逐点比较求出四种非晶合金饱和磁感应强度Bs最大磁导率max与压力的关系。发现：（1）总趋势是Bs和max都随压力增加而减小；（2）在2~3各压力区Bs和max皆呈现反常增高。（1）可归因于交换积分常数A随原子间距减小而减小，导致磁畴内自发磁化强度下降；（2）可能由于在某些窄的压力范围内静水压能够促进非晶合金微结构的短程有序化。Abstract: Magnetization curves and magnetic permeability of amorphous alloys FeCoNiSiVB, FeSiB, FeCrSiB, FeCoSiB in the hydrostatic pressure range of 0.000 1~2.4 GPa were investigated. Besides, the relation between pressure and the maximum magnetic permeability max of the four alloys was obtained with accurate fitting of the polynomial and comparing of computer one by one. It is found that (1) for intensity of magnetic induction Bs the general trend is to decrease with the increase of pressure; (2) in 2~3 pressure range, Bs presents a anomalous rise. In our discussion, (1) is due to the fact that exchange-integral constant A drops with the reduction of atomic interval, which causes the intensity of spontaneous magnetization to descend in magnetic domain; (2) probably comes from some changes of chemical short range order in microscopic structures of amorphous alloys at high pressure.
