PROBLEM TO BE SOLVED: To provide a method for analyzing micromagnetization with increased analysis accuracy by allocating a micromagnetization vector to the center of mesh divided microelements, solving an LLG equation and a magnetic field equation at the same time every time step, and conducting the analysis while taking into consideration previously neglected magnetic properties such as magnetic anisotropy. SOLUTION: A computer is caused to implement a procedure 1 for receiving the input of parameters of micromagnetization allocated to the center of subdivided elements and vector potentials allocated to the sides or nodal points of the elements; a procedure 2 for creating a magnetic field equation that imparts an external magnetic field for micromagnetization; a procedure 3 for finding a solution of the magnetic field equation; a procedure 4 for time-integrating the LLG equation using the solution; a procedure 5 for determining whether or not the micromagnetization obtained through the procedure 4 satisfies conversion requirements; a procedure 6 for correcting the magnetic field equation to increase time in steps if the requirements are not satisfied; and a process-repeating procedure for repeating the processes from 3.
