Popis:	This paper introduces the application of the transmission line matrix (TLM) method for simulating thermal effects in magneto-optic multi-layers irradiated with a Gaussian laser beam. A model using linear heating compares favourably with an accepted semi-analytical treatment. Comparison with available experimental data suggests that thin film media of this type display a temperature-dependent, thermal conductivity. Simulations involving nonlinear heat flow have also been performed. Because there are no equivalent experimental data available for comparison, a series of tests with hypothetical data was undertaken. The results underline the urgent need for experimental measurements of the temperature-dependence of thermal conductivity in these materials.
