Ultrafast Optomagnetic Bistable Effects in Magnetically–Ordered Dielectrics Cylindrical Nanoparticles

Abstract

We present results of a study of the magnetization orientation in magnetically–ordered dielectrics cylindrical nanoparticles. We derive the hysteresis dependence of the equilibrium magnetization orientation X on the external parameter p. This hysteresis determines the region for the optical bistability observation in the opto-magnetic inverse Faraday effect.
