PROBLEM TO BE SOLVED: To improve the calculation accuracy of a micro-magnetic simulation.SOLUTION: An effective magnetic field calculation unit 6 has an external magnetic field calculation unit 9, a diamagnetic field calculation unit 10, and an intermediate magnetization utilization unit 11, and the intermediate magnetization utilization unit 11 has an intermediate magnetization calculation unit 21, an exchange coupling field calculation unit 22, and an anisotropy field calculation unit 23. The intermediate magnetization calculation unit 21 calculates a magnetization vector at an intermediate point between adjacent elements as intermediate magnetization, and the exchange coupling field calculation unit 22 and the anisotropy field calculation unit 23 calculate an exchange coupling field and an anisotropy field using the intermediate magnetization, respectively. The intermediate magnetization calculation unit 21 assumes the magnitude of the magnetization vector of the intermediate magnetization to be 1.SELECTED DRAWING: Figure 1 |
