Journal ArticleDOI
All-optical magnetic recording with circularly polarized light.
C.D. Stanciu,Fredrik Hansteen,Alexey Kimel,Andrei Kirilyuk,Arata Tsukamoto,Akiyoshi Itoh,Theo Rasing +6 more
TL;DR: It is experimentally demonstrate that the magnetization can be reversed in a reproducible manner by a single 40 femtosecond circularly polarized laser pulse, without any applied magnetic field, revealing an ultrafast and efficient pathway for writing magnetic bits at record-breaking speeds.
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
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 Path for Optical Magnetization Reversal via a Strongly Nonequilibrium State
K. Vahaplar,Alexandra M. Kalashnikova,Alexandra M. Kalashnikova,Alexey Kimel,Denise Hinzke,Ulrich Nowak,Roy W. Chantrell,Arata Tsukamoto,Arata Tsukamoto,Akiyoshi Itoh,Andrei Kirilyuk,Theo Rasing +11 more
TL;DR: Using time-resolved single-shot pump-probe microscopy the mechanism and the time scale of all-optical magnetization reversal by a single circularly polarized 100 fs laser pulse are unveiled and it is demonstrated that for a 5 microm domain the magnetic information can be recorded and readout within 30 ps, which is the fastest "write-read" event demonstrated for magnetic recording so far.
Journal ArticleDOI
Fast domain wall motion in the vicinity of the angular momentum compensation temperature of ferrimagnets.
Kab-Jin Kim,Se Kwon Kim,Yuushou Hirata,Se Hyeok Oh,Takayuki Tono,Duck-Ho Kim,Takaya Okuno,Woo Seung Ham,Sanghoon Kim,Gyoungchoon Go,Yaroslav Tserkovnyak,Arata Tsukamoto,Takahiro Moriyama,Kyung Jin Lee,Teruo Ono,Teruo Ono +15 more
TL;DR: This finding allows the physics of antiferromagnetic spin dynamics to be investigated and highlights the importance of tuning of the angular momentum compensation point of ferrimagnets, which could be a key towards ferrimagnetic spintronics.
