Nonlinear wave propagation through a ferromagnet with damping in (2+1) dimensions

We investigate how dissipation and nonlinearity can affect the electromagne tic wave propagating through a saturated ferromagnet in the presence of an external magnetic field in (2 + 1) dimensions. The propagation of electroma gnetic waves through a ferromagnet under an external magnetic field in the presence of dissipative effect has been studied using reductive perturbatio n method. It is found that to the lowest order of perturbation the system o f equations for the electromagnetic waves in a ferromagnet can be reduced t o an integro-differential equation.
