Mathematical modelling of ferromagnetic overlayer with softened exchange surface integral

Spin waves theory is one of important concept in surface physics study. Its concept becomes a method to study the low-temperature properties of magnetic materials with ordered magnetic moments. In this study, our scope will be on the discussion of spin wave theory at ferromagnetic overlayer. Green’s...
