Transverse susceptibility for single-domain particle with cubic anisotropy

Abstract

For the uniaxial single-domain particles a 2D critical approach can be used for the calculation of the transverse susceptibility (TS) signal. The TS for cubic anisotropy is essentially a 3D problem that was solved with a micromagnetic Landau–Lifshitz–Gilbert algorithm. Since the TS experimental method is extensively used in the laboratories for the anisotropy evaluation, the study value consists of the fact that it offers a tool for understanding the problems and errors in the correctinterpretation of the TS curves when particles with cubic anisotropies are involved.
