Abstract
Using the retarded Green’s function technique (RGFT) and the linear spin wave approximation (LSWA), the magnetic properties of an intralayer ferri(antiferro)magnetic double-layer Heisenberg system were investigated. The calculation results indicate that spin values, exchange couplings and anisotropies have a great influence on the spin-wave spectra (SWS), energy gap, frequency in middle of magnon energy gap, sublattiec magnetizations and quantum fluctuations of the system. Owing to the competition between the exchange coupling and anisotropy, the sublattice magnetizations or quantum fluctuations cross.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
