铁磁金属的表面阻抗与自旋波共振

本文计算了铁磁金属在平行磁场中的表面阻抗。计算中考虑了交换作用所引起的磁化率空间色散及趋肤效应的反常性。分别讨论了磁矩的两种边界条件m=0和(?m)/(?n)=0。同时研究了导电电子在表面散射性质的影响。利用Азбель-Канер在迴旋共振理论中的方法,计算了考虑电导率旋磁性条件下的表面阻抗。

SURFACE IMPEDANCE OF FERROMAGNETIC METALS AND SPIN-WAVE RESONANCE

The surface impedance of a ferromagnetic metal in a parallel magnetic field has been calculated. Both exchange interaction and the anomalous character of skin-effect havebeen taken into account. Calculation has been carried out for both the "exchange" boun-dary condition (?m)/(?n)=0 and the "pinning" condition m = 0 for the magnetic moment.The influence of the boundary scattering character of conduction electrons has been also considered. Furthermore, by making use of the Aзбелъ-KaHep method in the theory of cyclotron resonance the surface impedance has been evaluated with the gyrotropy of the electrical conductivity taken into account.
