我们研究了铁磁富铁合金的非晶态或部分结晶样品中应力退火引起的单轴各向异性。在 10-300 K 的温度范围内测量和研究了几种矫顽力特性。发现由于磁畴壁平移而产生的矫顽力贡献很大程度上取决于晶相的数量和诱导的各向异性的大小。主要与域成核相关的矫顽力贡献似乎与这两个因素无关。所研究合金的所有磁性能（磁化强度、各向异性和矫顽力参数）在研究的温度范围内都非常稳定。
We have examined the uniaxial anisotropy induced by stress-annealing in amorphous or partially crystallized samples of ferromagnetic Fe-rich alloys. Several coercivity characteristics were measured and investigated in the temperature range 10–300 K. The coercivity contribution due to domain wall translations was found to be strongly dependent on the amount of the crystalline phase and on the magnitude of the induced anisotropy. The coercivity contribution connected predominantly with the domain nucleation appears to be independent of these two factors. All of the magnetic properties (magnetization, anisotropy and coercivity parameters) of the studied alloys were very stable within the temperature ranges investigated.
