Dipolar ferromagnetism in three-dimensional superlattices of nanoparticles
B. Alkadour, J. I. Mercer, J. P. Whitehead +2
A series of atomistic finite temperature simulations on a model of an FCC lattice of maghemite nanoparticles using the stochastic Landau-Lifshitz-Gilbert (sLLG) equation are presen…
Kinetic Monte Carlo Simulations of the Effect of the Exchange Control Layer Thickness in CoPtCrB/CoPtCrSiO Granular Media
Ahmad M. Almudallal, J. I. Mercer, J. P. Whitehead +2
A hybrid kMC/LLG algorithm is used to simulate experimental MH hysteresis loops for dual layer ECC media. The calculation of the rate coefficients and difficulties arising from low…
Thermally activated switching at long time scales in exchange-coupled magnetic grains
Ahmad M. Almudallal, J. I. Mercer, J. P. Whitehead +3
Rate coefficients of the Arrhenius-Neel form are calculated for thermally activated magnetic moment reversal for dual layer exchange-coupled composite (ECC) media based on the Lang…
Atomic level micromagnetic model of recording media switching at elevated temperatures
J. I. Mercer, M. L. Plumer, J. P. Whitehead +1
An atomic level micromagnetic model of granular recording media is developed and applied to examine external field-induced grain switching at elevated temperatures which captures n…
