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…
Micromagnetic simulations of sweep-rate dependent coercivity in perpendicular recording media
M. L. Plumer, M. D. Leblanc, J. P. Whitehead +1
The results of micromagnetic simulations are presented which examine the impact of thermal fluctuations on sweep rate dependent coercivities of both single-layer and exchange-coupl…
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…
New Paradigms in Magnetic Recording
M. L. Plumer, J. van Ek, W. C. Cain
The magnetic hard disc drive industry continues to face serious challenges in its quest for ever decreasing bit size. This review summarizes recent advances and promising new techn…
Resistivity due to low-symmetrical defects in metals
J. P. Dekker, A. Lodder, J. van Ek
The impurity resistivity, also known as the residual resistivity, is calculated ab initio using multiple-scattering theory. The mean-free path is calculated by solving the Boltzman…
Theory for the electromigration wind force in dilute alloys
J. P. Dekker, A. Lodder, J. van Ek
A multiple scattering formulation for the electromigration wind force on atoms in dilute alloys is developed. The theory describes electromigration via a vacancy mechanism. The met…
