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.
