Impact of Anisotropic Exchange on M-H Loops: Application to ECC Media

Micromagnetic simulation results on Co-based recording media are presented which examine the impact of a modified near-neighbor exchange interaction between grains of the form J z (M i z M j z ), reflecting the hexagonal crystal symmetry. Both out-of-plane and in-plane M-H loops are calculated, with...
