Modeling coupled spin and lattice dynamics
Mara Strungaru, Matthew O A Ellis, Sergiu Ruta +3
A unified model of molecular and atomistic spin dynamics is presented enabling simulations both in microcanonical and canonical ensembles without the necessity of additional phenom…
Role of longitudinal fluctuations in L FePt
Matthew O. A. Ellis, Mario Galante, Stefano Sanvito
L FePt is a technologically important material for a range of novel data storage applications. In the ordered FePt structure the normally non-magnetic Pt ion acquires a magnet…
Non-trivial spatial dependence of the spin torques in L1 FePt-based tunnelling junctions
Mario Galante, Matthew O. A. Ellis, Stefano Sanvito
We present an {\it ab-initio} study of the spin-transfer torque in a Fe/MgO/FePt/Fe magnetic tunnel junctions. We consider a FePt film with a thickness up to six unit cells, either…
Manifestation of higher-order inter-granular exchange in magnetic recording media
Matthew O. A. Ellis, Razvan. -V. Ababei, Roger Wood +2
Exchange coupling between magnetic grains is essential for maintaining the stability of stored information in magnetic recording media. Using an atomistic spin model, we have inves…
Switching times of nanoscale FePt: finite size effects on linear reversal mechanism
M. O. A. Ellis, R. W. Chantrell
The linear reversal mechanism in FePt grains ranging from 2.316 nm to 5.404 nm has been simulated using atomistic spin dynamics, parametrized from ab-initio calculations. The Curie…
