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
Ultrafast nonthermal photo-magnetic recording in a transparent medium
TL;DR: This work describes ultrafast all-optical photo-magnetic recording in transparent films of the dielectric cobalt-substituted garnet, which outperforms existing alternatives in terms of the speed of the write–read magnetic recording event and the unprecedentedly low heat load.
Journal ArticleDOI
Ultrafast spin dynamics in multisublattice magnets.
J.H. Mentink,Johan Hellsvik,D. Afanasiev,Boris A. Ivanov,Andrei Kirilyuk,Alexey Kimel,Olle Eriksson,Mikhail I. Katsnelson,Theo Rasing +8 more
TL;DR: In this article, a general theoretical framework for ultrafast laser-induced spin dynamics in multisublattice magnets is proposed, where the authors distinguish relaxation of relativistic and exchange origin and show that nonequivalent sublattices have distinct dynamics despite their strong exchange coupling.
Journal ArticleDOI
Ultrafast control of magnetic interactions via light-driven phonons.
D. Afanasiev,J. R. Hortensius,Boris A. Ivanov,Boris A. Ivanov,Alireza Sasani,Eric Bousquet,Yaroslav Blanter,Rostislav Mikhaylovskiy,Alexey Kimel,Andrea D. Caviglia +9 more
TL;DR: In this paper, it was shown that light-driven phonons can be utilized to coherently manipulate macroscopic magnetic states, and the potential of resonant phonon excitation for the manipulation of ferroic order on ultrafast timescales.
Journal ArticleDOI
Multiscale dynamics of helicity-dependent all-optical magnetization reversal in ferromagnetic Co/Pt multilayers
Rajasekhar Medapalli,D. Afanasiev,D. Afanasiev,Do Kyun Kim,Yassine Quessab,Yassine Quessab,Sohini Manna,S. A. Montoya,Andrei Kirilyuk,Th. Rasing,Alexey Kimel,Alexey Kimel,Eric E. Fullerton +12 more
TL;DR: In this article, the dynamics of the helicity-dependent all-optical switching (HD-AOS) of Co/Pt ferromagnetic multilayers were investigated.
