Distribution of the Antiferromagnetism Vector for an Isolated Antidot and a System of Remote Antidots in Antiferromagnets

Юрій Іванович Горобець, Оксана Юріївна Горобець, Володимир Вікторович Куліш


In the paper, an antiferromagnetism vector distribution in an antiferromagnetic film composed of an uniaxial or isotropic two-sublattice antiferromagnet with a set system of circular antidots is investigated. For such a system, the Landau-Lifshitz equation is written and its solution is obtained. An antiferromagnetism vector distribution is found for three isolated antidot cases (in isotropic antiferromagnet, in “easy plane” antiferromagnet, in “easy axis” antiferromagnet) with vortex-type boundary conditions on the antidot surface and three cases of remote antidotes system (in isotropic antiferromagnet, in “easy plane” antiferromagnet and in “easy axis” antiferromagnet) with vortex-type boundary conditions on the surface of one of the antidots. It is shown that the plane distribution of the antiferromagnetism vector on at least one cross-section of one of the antidots is possible only in the case of the antidots remoteness.
