FMR in thin permalloy films with small surface anisotropy
Abstract
The excitation of low energy spin waves in permalloy films was studied by FMR at room temperature in the interval 9-80 GHz. The values of exchange constant and surface anisotropy were found frequency independent, the linewidths, at given frequency, do not depend on the spin wave mode number.
