Abstract:
The switching speed of a granular perpendicular recording medium is investigated using finite-element micromagnetic calculations. The switching behavior sensitively depends on the intergrain exchange coupling, the grain-size distribution, and the degree of alignment of easy axes. These effects are investigated using subgrain discretization. In irregular microstructures the switching time decreases considerably with decreasing intergrain exchange.
