<P>PROBLEM TO BE SOLVED: To provide a calculation program, calculation method and calculation apparatus of magnetic exchange coupling energy capable of calculating a magnetic exchange coupling field with a high degree of accuracy in the case where the magnetization vector of a rotation angle is larger than ever before. <P>SOLUTION: The simulation program includes the steps of: linearly interpolating a rotation angle between two magnetization vectors M<SB POS="POST">i</SB>, M<SB POS="POST">j</SB>disposed at the respective centers of two adjacent elements used in a finite volume method with reference to a rotation axis u perpendicular to the two magnetization vectors M<SB POS="POST">i</SB>, M<SB POS="POST">j</SB>; and calculating a magnetic exchange coupling field by integrating a magnetic field acting as a force exerted on the two magnetization vectors M<SB POS="POST">i</SB>, M<SB POS="POST">j</SB>with the linearly interpolated rotation angle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
