Journal ArticleDOI
Transient ferromagnetic-like state mediating ultrafast reversal of antiferromagnetically coupled spins
Ilie Radu,K. Vahaplar,Christian Stamm,Torsten Kachel,Niko Pontius,Hermann A. Dürr,Hermann A. Dürr,Thomas Ostler,Joseph Barker,Richard F. L. Evans,Roy W. Chantrell,Arata Tsukamoto,Arata Tsukamoto,Akiyoshi Itoh,Andrei Kirilyuk,Theo Rasing,Alexey Kimel +16 more
TL;DR: It is found that the ultrafast spin reversal in GdFeCo, where spins are coupled antiferromagnetically, occurs by way of a transient ferromagnetic-like state, which provides a concept for the possibility of manipulating magnetic order on the timescale of the exchange interaction.
Journal ArticleDOI
Atomistic spin model simulations of magnetic nanomaterials.
Richard F. L. Evans,W. J. Fan,P. Chureemart,Thomas Ostler,Matthew O. A. Ellis,Roy W. Chantrell +5 more
TL;DR: The key methods used in atomistic spin models are presented, which are then applied to a range of magnetic problems, and the parallelization strategies used enable the routine simulation of extended systems with full atomistic resolution.
Journal ArticleDOI
Ultrafast heating as a sufficient stimulus for magnetization reversal in a ferrimagnet.
Thomas Ostler,Joseph Barker,Richard F. L. Evans,Roy W. Chantrell,Unai Atxitia,Oksana Chubykalo-Fesenko,S. El Moussaoui,L. Le Guyader,E. Mengotti,Laura J. Heyderman,F. Nolting,Arata Tsukamoto,Akiyoshi Itoh,D. Afanasiev,Boris A. Ivanov,Alexandra M. Kalashnikova,K. Vahaplar,J.H. Mentink,Andrei Kirilyuk,Theo Rasing,Alexey Kimel +20 more
TL;DR: Numerically and experimentally a novel mechanism of deterministic magnetization reversal in a ferrimagnet driven by an ultrafast heating of the medium resulting from the absorption of a sub-picosecond laser pulse without the presence of a magnetic field is shown.
Journal ArticleDOI
Newtype single-layer magnetic semiconductor in transition-metal dichalcogenides VX 2 (X = S, Se and Te)
Huei Ru Fuh,Ching-Ray Chang,Yin-Kuo Wang,Richard F. L. Evans,Roy W. Chantrell,Horng-Tay Jeng +5 more
TL;DR: Combining the semiconducting energy gap, the 100% spin polarized valence and conduction bands, the room temperature TC, and the in-plane magnetic anisotropy together in a single layer VX2, this newtype 2D magnetic semiconductor shows great potential in future spintronics.
Journal ArticleDOI
Stochastic form of the Landau-Lifshitz-Bloch equation
Richard F. L. Evans,Denise Hinzke,Unai Atxitia,Ulrich Nowak,Roy W. Chantrell,Oksana Chubykalo-Fesenko +5 more
TL;DR: In this article, two stochastic forms of the Landau-Lifshitzitz-Bloch equation are discussed and compared with the Boltzmann distribution at high temperatures.
