Аннотация

We present an algorithm for the numeric calculation of antiferromagnetic resonance frequencies for the noncollinear antiferromagnets of general type. This algorithm uses general exchange symmetry approach (Andreev and Marchenko, Sov. Phys. Usp. 130:39, 1980) 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, available for download. Program codes are tested against some representative analytically solvable cases.
