Abstract
The life time of a resonance spin wave has been studied in ferromagnetic transition metals utilizing the theory of generalized Brown's motion. A basic assumption is the exchange interaction of 3d electrons with the damped excitations of 4s electron spins. It is shown, that a result can be obtained in a form, which is simpler and physically more evident than the one derived using Green's functions.
