Micromagnetic study of longitudinal thin film media: effect of grain size distribution

Micromagnetic simulations have been performed to compare longitudinal thin film media with and without a grain size distribution. Hysteresis loops and dibit recordings are evaluated for various exchange interactions. The results show that the grain size distribution reduces the effect of the exchang...

Zusammenfassung:Micromagnetic simulations have been performed to compare longitudinal thin film media with and without a grain size distribution. Hysteresis loops and dibit recordings are evaluated for various exchange interactions. The results show that the grain size distribution reduces the effect of the exchange interaction.
