Nonlinear TM Surface waves along a single interface of antiferromagnet and superconductor structure

Abstract

We study theoretically the nonlinear frequency characteristics of the transverse magnetic surface waves on the interface of an antiferromagnet and superconductor structure. The complex wave number of TM wave is computed by solving the dispersion equation in order to find out the effect of the temperature of superconductor on the reduced phase and attenuation constants. Both effects of the nonlinearity and the temperature of superconductor have been studied on the power flow as a function of the reduced phase and attenuation constants.
