摘要
用磁转矩和磁化功方法测定Fe_(40)Ni_(40)P_(12)B_3和(Fe_(0.1)CO_(0.5Ni_(0.4))_(78)Si_6B_(16)非晶态合金带在制备态及退火后的磁各向异性常数。结果表明,用磁转矩方法测定的制备态非晶带中的平面磁各向异性常数,其中大部分是不因退火而改变的,这部分的磁各向异性对合金的技术磁化曲线无明显影响。
The in-plane magnetic anisotropy constants of Fe40Ni40P12B8 and (Fe0.1Co0.5N(?))(?) Si6B16 amorphous alloy ribbons in the as-quenched and annealed state have been measured with the torque magnetometer and the work of magnetization methods. The results show that the main part of the anisotropy constant measured by the torque magnetometer method for the as-quenched samples does not change after annealing and this part of anisotropy almost produces no influence on the magnetization curve.
