Journal ArticleDOI
Magnetic vortex core reversal by excitation with short bursts of an alternating field
B. Van Waeyenberge,A. Puzic,Hermann Stoll,Kang Wei Chou,Tolek Tyliszczak,Riccardo Hertel,Manfred Fähnle,H. Bruckl,Karsten Rott,Günter Reiss,Ingo Neudecker,Dieter Weiss,Christian H. Back,Gisela Schütz +13 more
TL;DR: It is demonstrated that the sense of gyration of the vortex structure can be reversed by applying short bursts of the sinusoidal excitation field with amplitude of about 1.5 mT, unambiguously indicates a switching of the out-of-plane core polarization.
Journal ArticleDOI
Time-resolved x-ray microscopy of spin-torque-induced magnetic vortex gyration.
Markus Bolte,Guido Meier,Benjamin Krüger,André Drews,René Eiselt,Lars Bocklage,Stellan Bohlens,Tolek Tyliszczak,Arne Vansteenkiste,Bartel Van Waeyenberge,Bartel Van Waeyenberge,Kang Wei Chou,A. Puzic,Hermann Stoll +13 more
TL;DR: Time-resolved x-ray microscopy is used to image the influence of alternating high-density currents on the magnetization dynamics of ferromagnetic vortices, and spin-torque-induced vortex gyration is observed in micrometer-sized permalloy squares.
Journal ArticleDOI
Spatially resolved ferromagnetic resonance : Imaging of ferromagnetic eigenmodes
A. Puzic,Bartel Van Waeyenberge,Kang Wei Chou,Peter Fischer,Hermann Stoll,Gisela Schütz,T. Tyliszczak,Karsten Rott,Hubert Brückl,Günter Reiss,Ingo Neudecker,Thomas Haug,Matthias Buess,Christian H. Back +13 more
TL;DR: In this article, a frequency-domain spatially resolved ferromagnetic resonance (SR-FMR) technique was applied to magnetic x-ray microscopy to study the magnetization dynamics on sub-micron length scales.
Journal ArticleDOI
Vortex dynamics in coupled ferromagnetic multilayer structures
Kang Wei Chou,A. Puzic,Hermann Stoll,Gisela Schütz,Bartel Van Waeyenberge,T. Tyliszczak,Karsten Rott,Günter Reiss,Hubert Brückl,Ingo Neudecker,Dieter Weiss,Christian H. Back +11 more
TL;DR: In this article, a 1×1μm2 trilayer structure consisting of Co(20nm)∕Cu(10nm) ∕Permalloy Ni80Fe20(20 nm) was studied by time-resolved transmission x-ray microscopy.
Journal ArticleDOI
Direct observation of the vortex core magnetization and its dynamics
Kang Wei Chou,A. Puzic,Hermann Stoll,D. Dolgos,Gisela Schütz,B. Van Waeyenberge,Arne Vansteenkiste,T. Tyliszczak,Georg Woltersdorf,Christian H. Back +9 more
TL;DR: In this article, the direction of the out-of-plane magnetization in the vortex core (up or down) was directly visualized in 500×500nm2, 40nm thick soft magnetic Ni-Fe samples.
