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

TL;DR: This article reviews static and dynamic interfacial effects in magnetism, focusing on interfacially-driven magnetic effects and phenomena associated with spin-orbit coupling and intrinsic symmetry breaking at interfaces, identifying the most exciting new scientific results and pointing to promising future research directions.
Journal ArticleDOI

Christian Stamm,Torsten Kachel,Niko Pontius,Rolf Mitzner,T. Quast,Karsten Holldack,S. Khan,C. Lupulescu,Emad F. Aziz,M. Wietstruk,Hermann A. Dürr,Wolfgang Eberhardt +11 more
TL;DR: It is shown that an efficient novel channel for angular momentum dissipation to the lattice can be opened by femtosecond laser excitation of a ferromagnet, and for the first time, the quenching of spin angular momentum and its transfer toThe lattice with a time constant of 120+/-70 fs is determined unambiguously with X-ray magnetic circular dichroism.
Journal ArticleDOI
Control of the metal-insulator transition in vanadium dioxide by modifying orbital occupancy
Nagaphani Aetukuri,Nagaphani Aetukuri,Alexander X. Gray,Marc Drouard,Matteo Cossale,Li Gao,Alexander H. Reid,Roopali Kukreja,Roopali Kukreja,Hendrik Ohldag,Catherine Jenkins,Elke Arenholz,Kevin P. Roche,Hermann A. Dürr,Mahesh G. Samant,Stuart S. P. Parkin +15 more
TL;DR: In this article, it was shown that by putting a thin layer of vanadium dioxide on a buffer, and varying the buffer's thickness, the orbital occupancy in the metallic state and the transition temperature can be tuned.
Journal ArticleDOI
Distinguishing the ultrafast dynamics of spin and orbital moments in solids
Christine Boeglin,Eric Beaurepaire,V. Halté,Victor Lopez-Flores,Christian Stamm,Niko Pontius,Hermann A. Dürr,Hermann A. Dürr,Jean-Yves Bigot +8 more
TL;DR: The important role played by the spin–orbit interaction in the ultrafast laser-induced demagnetization of ferromagnetic films is highlighted, and it is shown that the magneto-crystalline anisotropy energy is an important quantity to consider in such processes.
