Analysis of Switching in Uniformly Magnetized Bodies (2008)
Michael J. Donahue, Donald G. Porter
Abstract — A full analysis of magnetization reversal of a uniformly magnetized body by coherent rotation is presented. The magnetic energy of the body in the presence of an applied field H is...
Analysis of Switching in Uniformly Magnetized Bodies (2002)
Michael J. Donahue, Donald G. Porter
A full analysis of magnetization reversal of a uniformly magnetized body by coherent rotation is presented. The magnetic energy of the body in the presence of an applied eld H is modeled as E = ( 0...
Analytical Determination of the LLG Zero-Damping Critical Switching Field (1998)
Previous numerical studies based on the Landau-Lifshitz-Gilbert (LLG) equation have considered the magnetization reversal of a uniaxial, singledomain particle due to an applied field pulse with a...
