摘要/Abstract

摘要： 用电子自旋共振实验研究La_0.65Ba_0.35MnO₃(LBMO)薄膜的磁性,从磁性膜的各向异性铁磁共振谱得到不同角度θ_h时的共振磁场B_r,求出样品的等效磁场B_eff及旅磁比γ,并通过样品的饱和磁化强度M_s,求出各向异性常数K.

Abstract: The magnetic properties of La_0.65Ba_0.35MnO₃(LBMO) thin film have been studied by use of Electron-Spin-Resonance (ESR) method, resonance magnetic field B_r of various angles θ_h were obtained from the anisotropic FMR spectrum, and from the calculated results of B_eff and γ the anisotropic constant K of the sample was also evaluated by use of its saturation magnetization M_s.
