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
Building blocks of an artificial kagome spin ice : Photoemission electron microscopy of arrays of ferromagnetic islands
E. Mengotti,Laura J. Heyderman,A. Fraile Rodríguez,André Bisig,L. Le Guyader,Frithjof Nolting,Hans-Benjamin Braun +6 more
TL;DR: In this paper, the magnetic configurations in three basic building blocks of an artificial kagome spin ice consisting of one, two, and three rings are examined with photo-emission electron microscopy.
Journal ArticleDOI
Controlling optical transmission through magneto-plasmonic crystals with an external magnetic field
Gregory A. Wurtz,Gregory A. Wurtz,William Hendren,Robert Pollard,R. Atkinson,L. Le Guyader,Andrei Kirilyuk,Theo Rasing,Igor I. Smolyaninov,Anatoly V. Zayats +9 more
TL;DR: The magneto-optical properties of surface-plasmon polaritonic crystals on ferromagnetic substrates have been studied in this article, showing that the resonant optical transmission can be efficiently controlled with the applied static magnetic field.
Journal ArticleDOI
Nanoscale sub-100 picosecond all-optical magnetization switching in GdFeCo microstructures
L. Le Guyader,L. Le Guyader,Matteo Savoini,Matteo Savoini,S. El Moussaoui,S. El Moussaoui,Michele Buzzi,Arata Tsukamoto,Akiyoshi Itoh,Andrei Kirilyuk,Theo Rasing,Alexey Kimel,Frithjof Nolting +12 more
TL;DR: Time-resolved photo-emission electron microscopy studies reveal that nanoscale magnetic switching employing such focusing can be pushed to the sub-100 ps regime, providing a path to sub-wavelength magnetic recording.
Journal ArticleDOI
FemtoSpeX: a versatile optical pump–soft X-ray probe facility with 100 fs X-ray pulses of variable polarization
