V. Glazkov, T. Soldatov, Yu. Krasnikova

摘要:

本文提出了一种数值计算非共线一般反铁磁体反铁磁共振频率的算法。该算法采用一般的交换对称方法\cite{andrmar},适用于描述弱场中任意非共线自旋结构的低能动力学。算法实现为MatLab和C++程序代码,可供下载。程序代码进行了测试,对一些有代表性的分析可解决的情况下。

英文摘要:

We present an algorithm for the numeric calculation of antiferromagnetic resonance frequencies for the non-collinear antiferromagnets of general type. This algorithm uses general exchange symmetry approach \cite{andrmar} and is applicable for description of low-energy dynamics of an arbitrary noncollinear spin structure in weak fields. Algorithm is implemented as a MatLab and C++ program codes, which are available for download. Program codes are tested against some representative analytically solvable cases.
