Coherent phonon transport and minimum of thermal conductivity in LaMnO/SrMnO superlattices
Dennis Meyer, Daniel Metternich, Pia Henning +5
In this Letter, we present investigations of thermal transport in (LaMnO)/(SrMnO) superlattices (SLs) with SL periods between and unit cells. The an…
Orbital order phase transition in probed by photovoltaics
B. Kressdorf, T. Meyer, M. ten Brink +13
The phase diagram of is modified x 0.3, which suggests a reevaluation of the phase diagram of other manganites in that doping region. Rather than an orbit…
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…
Atomic scale spectral control of thermal transport in phononic crystal superlattices
D. Meyer, V. Roddatis, J. P. Bange +12
We present experimental and theoretical investigations of phonon thermal transport in (LaMnO)/(SrMnO) superlattices (LMO/SMO SLs) with the thickness of individual l…
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…
Nanoscale mapping of ultrafast magnetization dynamics with femtosecond Lorentz microscopy
Nara Rubiano da Silva, Marcel Möller, Armin Feist +3
Novel time-resolved imaging techniques for the investigation of ultrafast nanoscale magnetization dynamics are indispensable for further developments in light-controlled magnetism.…
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…
The building blocks of magnonics
Benjamin Lenk, Henning Ulrichs, Fabian Garbs +1
Novel material properties can be realized by designing waves' dispersion relations in artificial crystals. The crystal's structural length scales may range from nano- (light) up to…
