APPLICATION OF THERMODYNAMICAL RETARDED GREEN FUNCTION TO THE THEORY OF LINE WIDTH OF FERROMAGNETIC RESONANCE
热力学的推迟格临函数对铁磁共振峰宽理论的应用

The theory of Clogston and his coworkers on the line width of ferromagnetic resonance is derived by using thermodynamical retarded Green functions. The results obtained are applicable for a wide range of temperatures. The susceptibility tensor and the cha
