摘要：
A non-transitory computer-readable recording medium stores a magnetic program causing a computer to perform an exchange coupling energy calculating process including interpolating a rotation angle between two magnetization vectors disposed at the respective centers of two adjacent elements used in a finite volume method with reference to a rotation axis perpendicular to the two magnetization vectors, and calculating a magnetic exchange coupling field by integrating a magnetic field acting as a force exerted on the two magnetization vectors with the interpolated rotation angle.
