Abstract

Relationship between coercivity and micromagnetic structure was estimated using a micromagnetic simulator assuming permalloy film as a magnetic film. Wire-like shaped magnetic film showed relatively high coercivity and the magnetization reversed thorough coherent rotation. Coercivity was found to relate to the micromagnetic structure, and large sized film tends to configure vortex micromagnetic structure and coercivity becomes small.
