From Chaotic Spin Dynamics to Non-collinear Spin Textures in YIG Nano-films by Spin Current Injection
Henning Ulrichs
In this article I report about a numerical investigation of nonlinear spin dynamics in a magnetic thin-film, made of Yttrium-Iron-Garnet (YIG). This film is exposed to a small in-p…
Spin-current manipulation of photoinduced magnetization dynamics in heavy metal / ferromagnet double layer based nanostructures
Steffen Wittrock, Dennis Meyer, Markus Müller +5
Spin currents offer a way to control static and dynamic magnetic properties, and therefore they are crucial for next-generation MRAM devices or spin-torque oscillators. Manipulatin…
Micromagnetic view on ultrafast magnon generation by femtosecond spin current pulses
Henning Ulrichs, Ilya Razdolski
In this Article we discuss a micromagnetic modelling approach to describe the ultrafast spin-transfer torque excitation of coherent and incoherent magnons on the nanoscale. Impleme…
Anomalous Nernst effect on the nanometer scale: Exploring three-dimensional temperature gradients in magnetic tunnel junctions
Ulrike Martens, Torsten Huebner, Henning Ulrichs +8
Localized laser heating creates temperature gradients in all directions and thus leads to three-dimensional electron flux in metallic materials. Temperature gradients in combinatio…
Magnetization dynamics in magnonic structures with different geometries: interfaces, notches and waveguides
M. Mansurova, J. von der Haar, J. Panke +3
The discovery of the ultrafast magnetization dynamics twenty years ago has led to a broad variety of experimental techniques to explore phenomena in magnetic materials with high te…
A light induced metastable magnetic texture uncovered by in-situ Lorentz microscopy
Tim Eggebrecht, Marcel Möller, J. Gregor Gatzmann +7
Magnetic topological defects, including vortices and Skyrmions, can be stabilized as equilibrium structures by tuning intrinsic magnetic interactions and stray field geometries. He…
Magnetization switching of FePt nanoparticle recording medium by femtosecond laser pulses
R. John, M. Berritta, D. Hinzke +11
Manipulation of magnetization with ultrashort laser pulses is promising for information storage device applications. The dynamic of the magnetization response depends on the energy…
Photo-magnonics
Benjamin Lenk, Fabian Garbs, Henning Ulrichs +2
In the framework of magnonics all-optical femtosecond laser experiments are used to study spin waves and their relaxation paths. Magnonic crystal structures based on antidots allow…
