摘要：

We investigated the thermal relaxation of isotropic and oriented media having the same k(u)V/kT via a method combining micromagnetic and Monte Carlo simulations and experiments. Through simulations and experiments, we ascertained that the thermal stability of remanent magnetization increases with increased circumferential orientation. We also confirmed via simulations that written dibit and continuous bits are thermally stabilized by circumferential orientation media. (C) 1999 Elsevier Science B.V. All rights reserved.
