At low magnetic field, the effects of magnetic-field-induced confining potential on the main features of the excitonic spectra are negligible.

在较低磁场下，其引入的限制势对激子吸收谱的主要特性的影响可以忽略。

Compared with anisotropic magnetoresistance effect and giant magnetoresistance effect, the sensitivity using HFMI technique is much higher at room temperature and in low magnetic field.

与各向异性磁阻效应和巨磁阻效应相比，高频磁阻抗效应传感技术灵敏度高、无巴克豪森噪声、适合常温、低磁场检测。
