Abstract: Micromagnetic simulation for perpendicular magnetic anisotropy CoxSiyBz substance which utilizes thermal activating for several parameter such as anisotropy constant and saturation magnetization parameter has been examined using Landau-Liftshitz Gilbert equation. Perpendicular Magnetic Anisotropy is used to realize storage medium with sizable capacity. However, it has a disadvantage in the need of a large writing field. Providing of heat can be used as a solution to lessen magnitude of writing field. At room temperature, combination value of anisotropy constant and saturation magnetization give impact to energy barrier, switching field and domain wall propagation rate in magnetization reversal. When nano-dot is heated at Curie temperature then cooled abruptly until room temperature, writing field is needed to reverse the magnetization has been successfully reduced up to ~ 90 %.
Keywords: anisotropy constant, saturation magnetization, probability, domain wall and reversal field
