2、 铁磁共振 -Ferromagnetic resonance(FMR) - 知乎专栏
2023年4月19日 · 磁性材料磁化后其总体可以等效合成为一个大磁矩,为研究这个大磁矩在磁场下的动力学问题,便有了这一个Landau-Lifshitz-Gilbert方程(LLG方程),这个方程在磁动力学中的地位相当高,就好像经典物理中的牛顿第二定律。 如下: \frac {\partial m} {\partial t}=-\gamma m \times H_ {eff}+\alpha m\times \frac {\partial m} {\partial t}. 这个方程本质上对应的是普通物理中的进动方程,等式的左边代表的是磁矩随时间的变化量。
Acoustically Driven Ferromagnetic Resonance in Diverse Ferromagnetic ...
2020年8月24日 · In FeCoSiB, we observe nonreciprocal SAW propagation. We also perform direct comparison of ADFMR and standard ferromagnetic resonance (FMR) on the same devices, revealing that ADFMR absorption is measurable even when FMR signals are extremely weak, and magnetic anisotropy does not fully explain asymmetry observed in ADFMR.
Analysis of the line shape of electrically detected ferromagnetic ...
2011年8月8日 · This work reviews and examines two particular issues related with the new technique of electrical detection of ferromagnetic resonance (FMR). This powerful technique has been broadly applied for studying magnetization and spin dynamics over the past ten years.
A ferromagnetic resonance (FMR) experiment consists in applying a microwave field to excite a single crystal sample in which the spins are strongly coupled by ferromagnetic exchange interactions, in the presence of an external mag-netic field. These interactions result from the combined effects of electrostatic
Ferromagnetic Resonance-Enhanced Electrically Small Antennas …
It is proposed that ferromagnetic resonance (FMR) of thin-film ferrites can be utilized to simultaneously improve the radiation efficiency and input impedance matching of electrically small antennas (ESAs). To validate the concept, the role of FMR in radiation is first derived analytically with an ideal thin-film ferrite radiator.
