AC Field-driven orientational crossover and energy dissipation in suspended magnetic nanoparticles
Iago López-Vázquez, Siraj Ul Haq, Kazuya Okada +4
By combining the Landau--Lifshitz--Gilbert equation with Brownian rotational dynamics of magnetic nanoparticles (MNPs), we theoretically investigate the role of particle rotation t…
Antiferromagnetic Switching in MnAu Using a Novel Laser Induced Optical Torque on Ultrafast Timescales
J. L. Ross, P-I. Gavriloaea, F. Freimuth +6
Efficient manipulation of the Néel vector in antiferromagnets can be induced by generation of spin orbit (SOT) or spin-transfer (STT) torques. Here we predict another possibility f…
Atomistic calculation of the thickness and temperature dependence of exchange coupling through a dilute magnetic oxide
R. F. L. Evans, Q. Coopman, S. Devos +3
The exchange coupling of two magnetic layers via a diffuse oxide interlayer is studied with an atomistic spin model. We investigate the effect of magnetic concentration and oxide l…
Two magnon bound state causes ultrafast thermally induced magnetisation switching
J. Barker, U. Atxitia, T. A. Ostler +3
There has been much interest recently in the discovery of thermally induced magnetisation switching, where a ferrimagnetic system can be switched deterministically without and appl…
Exchange coupling and magnetic anisotropy at Fe/FePt interfaces
C J Aas, P J Hasnip, R Cuadrado +4
We perform fully relativistic first principles calculations of the exchange interactions and the magnetocrystalline anisotropy energy (MAE) in an Fe/FePt/Fe sandwich system in orde…
Effects of composition and chemical disorder on the magnetocrystalline anisotropy of Fe_{x}Pt_{1-x} alloys
C. J. Aas, L. Szunyogh, R. W. Chantrell
We perform first principles calculations of the magnetocrystalline anisotropy energy (MAE) of the L1_{0}-like Fe_{x}Pt_{1-x} samples studied experimentally by Barmak and co-workers…
Laser induced magnetization switching in films with perpendicular anisotropy: a comparison between measurements and a multi-macrospin model
C. Bunce, J. Wu, G. Ju +5
Thermally-assisted ultra-fast magnetization reversal in a DC magnetic field for magnetic multilayer thin films with perpendicular anisotropy has been investigated in the time domai…
