摘要：
A hierarchical method for the calculation of interaction fields in micromagnetic models of materials is discussed. The method is shown to provide a substantial decrease in the number of calculations required, whilst overcoming some inherent disadvantages of the mean field calculation. The method is employed in a micromagnetic model of longitudinal thin film recording media, with which the effects of intergranular exchange coupling upon hysteresis properties and recorded transitions are investigated.
