Abstract

In this work, we have focused on the rotation mode and the energy barrier of material with K_u larger than 10⁷ erg/cm³. The Landau-Lifshitz-Gilbert equation was solved to find the mode. To consider incoherent mode properly, a magnetic grain was subdivided into lots of cubic cells with volume of (1 nm)³. The energy barrier was determined as the maximum energy difference during switching.
