The metamagnet consists of ferromagnetically ordered layers, with the intralayer ferromagnetic exchange interactions being much stronger than the weak antiferromagnetic interaction between adjacent layers. The calculations are carried out for the exchange-dominated regime within the framework of the Heisenberg model and taking into account the random phase approximation.
