Investigation on the Effect of an In-Plane Auxiliary Field on the SNR of HAMR Recording Systems

In this paper, we consider the application of an in-plane auxiliary field into the exchange-coupled composite medium in the heat-assisted magnetic recording (HAMR) system. The dynamic micromagnetic simulations are conducted based on the Landau-Lifshitz-Bloch equations and the signal-to-noise ratio (...
