原始语种摘要: Abstract(#br)Broadening of spin-wave modes in the ferromagnetic thin layer with temperature is investigated within the Born approximation in a coupled ferromagnetic/anti-ferromagnetic bilayer. The Damon–Eschbach mode is used as a model to calculate the frequency of spin-waves in the ferromagnetic layer. Exchange bias by interface coupling and a random magnetic field due to inhomgeneities of the interface are represented by an effective field. Within this model we can explain the observed broadening of spin wave modes with temperature.
