Paper Abstract

The first thermomagnetic hologram formation has been published by R.S. Mezrich /1/. The hologram is formed by the interference of two coherent light waves at thin recording medium, if regions of ferromagnetic recording material, corresponding to regions of high light intensity are heated above the Curie temperature. In these regions the direction of the magnetization is switched by bias magnetic field and/or demagnetization field of the ferromagnetic film. The process of magnetic hologram formation is an indirect one in that the temperature variation caused by the absorbed light intensity pattern leads to the final magnetization pattern. It is therefore of critical importance to determine the temperature profile in magnetic medium, caused by the incident light intensity pattern.
