Hartman effect for spin waves tunnelling through a barrier in a thin magnetic film is considered theoretically. The barrier is assumed to be created by a locally increased magnetic anisotropy field. The considerations are focused on a nanoscale system operating in the exchange-dominated regime. We derive the formula for group delay τ<sub>gr</sub> of a spin wave packet and show that τ<sub>gr</sub> saturates with increasing barrier width, which is a signature of the Hartman effect predicted earlie ...[more]
