Journal ArticleDOI
All-optical control of ferromagnetic thin films and nanostructures
C-H Lambert,C-H Lambert,Stéphane Mangin,Stéphane Mangin,B. S. D. Ch. S. Varaprasad,Yukiko Takahashi,Michel Hehn,Mirko Cinchetti,Gregory Malinowski,Kazuhiro Hono,Yeshaiahu Fainman,Martin Aeschlimann,Eric E. Fullerton +12 more
TL;DR: This work demonstrates optical control of ferromagnetic materials ranging from magnetic thin films to multilayers and even granular films being explored for ultra-high-density magnetic recording, and shows that Optical control of magnetic materials is a much more general phenomenon than previously assumed.
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
Nanoscale Magnetic Domains in Mesoscopic Magnets
Michel Hehn,K. Ounadjela,Jean-Pierre Bucher,F. Rousseaux,Dominique Decanini,Bernard Bartenlian,Claude Chappert +6 more
TL;DR: High-resolution magnetic force microscopy studies of magnetic submicrometer-sized cobalt dots with geometrical dimensions comparable to the width of magnetic domains reveal a variety of intricate domain patterns controlled by the details of the dot geometry.
Journal ArticleDOI
Giant Magnetoresistive Effects in a Single Element Magnetic Thin Film.

Journal ArticleDOI
Nanoscale magnetic domain structures in epitaxial cobalt films
TL;DR: The characteristic multidomain structure with perpendicular orientation predicted by Kittel is analyzed in high quality molecular beam epitaxy grown cobalt films of thicknesses varying from 10 to 500 nm for which the magnetic domain width is of the order of the film thickness.
