Аннотация: The exitation spectrum of a ferrimagnetic Heisenberg chain with four sublattices and twisting mutually ortoghonal easy planes is calculated using a diagram technique of atomic representation. It is shown that at low temperatures, the exitation spectrum of elementary excitations of the system is similar to the spectrum of a magnet wПоказать полностьюith an effective easy-axis type anisotropy directed along the line of easy plane intersection. © 2015, Allerton Press, Inc.
