摘要：

Spin-wave theory is used to investigate the magnetic properties of a Heisenbeg model consisting of ferro- and antiferromagnetic layers with antiferromagnetic interlayer coupling at finite temperatures. The sublattice magnetizations are calculated. It is shown that the temperature at which there is a crossover between sublattice magnetizations in each layer is affected by quantum fluctuations, thermal fluctuations and frustration of spins.
