Abstract
The properties of magnons created in FeCo/Cu multilayers are studied in the framework of the Heisenberg model. The excitation spectra, gap of creation, lifetimes, and magnetization are calculated. The magnetization agrees well with measured values, and it undergoes a 3D to 2D transition when the temperature increases.
