| Abstract: | Through spin wave theory the Hamiltonian with Heisenberg model of ferromagnetic antiferromagnetic double layers is deduced. Spin wave dispersion is obtained by using matrix motion equation in Green function.Internal energy of ferromagnetic antiferromagnetic double layers at low temperature is calculated numerically. |
