Landau-Lifshitz-Bloch-Slonczewski simulations of the spin-transfer-torque driven magnetization switching assisted by Joule heating

摘要

In this paper, we show that Landau-Lifshitz-Bloch-Slonczewski equation can be envisaged as one of the best options for the modeling of heat assisted spin transfer torque writing. The model is tested on a Joule assisted switching problem for a macrospin under a polarized current, with all the values for the parameters in the typical range used technologically. The switching diagram in the presence of the current is presented, explained, and the agreement with published experimental data is discussed.
