Journal ArticleDOI
Engineered materials for all-optical helicity-dependent magnetic switching.
Stéphane Mangin,Stéphane Mangin,Matthias Georg Gottwald,Charles-Henri Lambert,Charles-Henri Lambert,Daniel Steil,V. Uhlíř,L. Pang,Michel Hehn,Sabine Alebrand,Mirko Cinchetti,Gregory Malinowski,Gregory Malinowski,Yeshaiahu Fainman,Martin Aeschlimann,Eric E. Fullerton +15 more
TL;DR: It is demonstrated that all-optical helicity-dependent switching (AO-HDS) can be observed not only in selected rare earth-transition metal alloy films but also in a much broader variety of materials, including RE-TM alloys, multilayers and heterostructures.
Journal ArticleDOI
Analysis of oxygen induced anisotropy crossover in Pt/Co/MOx trilayers
Aurelien Manchon,Clarisse Ducruet,Lucien Lombard,Stéphane Auffret,B. Rodmacq,B. Dieny,Stefania Pizzini,Jan Vogel,V. Uhlíř,M. Hochstrasser,G. Panaccione +10 more
TL;DR: In this article, the role of plasma oxidation in the onset of magnetic anisotropy at the Co/MOx interface was investigated and it was observed that varying the oxidation time modifies the magnetic properties of the Co layer, inducing a magnetic aisotropic crossover from in-plane to out-of-plane.
Journal ArticleDOI
Dynamic switching of the spin circulation in tapered magnetic nanodisks
V. Uhlíř,V. Uhlíř,Michal Urbánek,L. Hladík,J. Spousta,Mi-Young Im,Peter Fischer,N. Eibagi,Jimmy Kan,Eric E. Fullerton,Tomáš Šikola +10 more
TL;DR: In this article, the authors show controlled dynamic switching of spin circulation in vortices using nanosecond field pulses by imaging the process with full-field soft X-ray transmission microscopy.
Journal ArticleDOI
Colossal magnetic phase transition asymmetry in mesoscale FeRh stripes.
TL;DR: It is shown that the first-order metamagnetic phase transition in FeRh films becomes strongly asymmetric in mesoscale structures, with pronounced supercooling and an avalanche-like abrupt transition from the ferromagnetic to the antiferromagnetic phase, while the reverse transition remains nearly continuous over a broad temperature range.
Journal ArticleDOI
Photoinduced Enhancement of the Charge Density Wave Amplitude.

TL;DR: It is demonstrated for the case of elemental chromium that moderate ultrafast photoexcitation can transiently enhance the charge-density-wave amplitude by up to 30% above its equilibrium value, while strong excitations lead to an oscillating, large-amplitude CDW state that persists above the equilibrium transition temperature.
