Abstract

We describe a 3D model to numerically evaluate the transient optical field in the case of MSR (Magnetic Super-Resolution) media. The first part of the model calculates the temperature profile in the media due to optical heating. The second part of the model calculates the transient magnetic parameters as a result of the temperature change. The third part of the model performs a simulation of the magnetization dynamics as a result of the change in the magnetic parameters. The fourth part of the model simulates the optical field during the transient magnetization dynamics.
