补充资料:磁各向异性
磁各向异性 magnetic anisotropy 物质的磁性随方向而变的现象。主要表现为弱磁体的磁化率及铁磁体的磁化曲线随磁化方向而变。铁磁体的磁各向异性尤为突出,是铁磁体的基本磁性之一。磁各向异性来源于磁晶体的各向异性。温度低于居里温度(见铁磁性)的铁磁体受外磁场作用时,单位体积物质达到磁饱和所需的能量称为磁晶能,由于晶体的各向异性,沿不同方向磁化所需的磁晶能不同。对每种铁磁体都存在一个所需磁晶能最小和最大的方向,前者称易磁化方向,后者称难磁化方向。铁磁体受外力作用时,由于磁弹性效应(见磁致伸缩),体内应力和应变的各向异性会导致磁各向异性。在外磁场或应力作用下的铁磁体进行冷、热加工处理时,均可产生感生磁各向异性。铁磁薄膜材料在一定外界条件影响下进行晶体生长时,也会引入生长磁各向异性。 |
