摘要: 研究了金属玻璃Fe_(78)Si_(10)B_(12)的磁化惑生各向异性常数K_(um)和应变感生各向异性常数K_(us)的350℃等温退火动力学行为和随测量温度T的变化,具有正值的K_(um)以lgta的线性函数随退火时间ta变化,而正比于M_s~(4.6)(T)随T变化,具有负值的K_(us)对于退火时张力的施加和去除作可逆的弛豫变化,而正比于M_s~(7.5)(T)随T变化,用一种畸变方向有序模型对结果作了定性解释。
Abstract:The 350℃ isothermal annealing kinetic behaviour and the temperature dependence of the magnetization-and strain-induced magnetic anisotropy constants, K_(um) and K_(us), of the metallic glass Fe_(78)Si_(10)B_(12) have been studied. The K_(um) of positive value varies with annealing time t_a as a linear function of lg t_a and with temperature T in proportion to M_s~(4.6)(T). However, the K_(us) of negative value varies reversibly in a relaxation manner when tension is applied to or removed from the annealed samples and with temperature T in proportion to M_s~(7.5)(T). The behaviour has been qualitatively interpreted using a distortion-directional ordering model.
