We have studied experimentally the interaction of nonlinear packets of spin waves with strongly localized nonuniformities of the static magnetic field representing magnetic potential barriers and wells. We have found that the nonlinearity in the system causes a noticeable modification of this interaction in comparison to the linear case. The strongest modification is observed under conditions where spin-wave envelope solitons are formed. Our findings show that for the case of potential barriers the solitons demonstrate an enhanced tunneling, whereas for potential wells they show an enhanced reflection. Moreover, the nonlinear enhancement of the interaction was found to be stronger for potential wells, which was associated with its resonant character.
