反映在宏观磁滞回线中的磁性由自旋矩和轨道矩两者主导。利用康普顿散射和超导量子干涉仪（SQUID）测量了Tb43Co57非晶薄膜的自旋磁滞回线（SSMH）和轨道磁滞回线（OSMH）。发现SSMH的形状不同于OSMH的形状，并且发现Co对SSMH的贡献不同于Tb。这些结果表明，磁开关可以是不同的自旋矩，轨道矩，甚至电子的状态。
The magnetic properties reflected in a macroscopic hysteresis loop are dominated by both spin and orbital moments. In this study, spin-specific magnetic hysteresis (SSMH) and orbital-specific magnetic hysteresis (OSMH) loops were obtained for amorphous Tb 43 Co 57 film by using a combination of Compton scattering and superconducting quantum interference device (SQUID) measurements. The shape of SSMH was found to be different from the shape of OSMH, and it was found that the contribution to SSMH from Co was different that from Tb. These results suggest that magnetic switching can be different among the spin moment, the orbital moment, and even the state of electrons.
