Magnetization dynamics in an exchange-coupled NiFe/CoFe bilayer studied by x-ray detected ferromagnetic resonance

Autor: G B G Stenning, L R Shelford, S A Cavill, F Hoffmann, M Haertinger, T Hesjedal, G Woltersdorf, G J Bowden, S A Gregory, C H Back, P A J de Groot, G van der Laan

Publikováno v: New Journal of Physics, Vol 17, Iss 1, p 013019 (2015)

Exchange-coupled hard and soft magnetic layers find extensive use in data storage applications, for which their dynamical response has great importance. With bulk techniques, such as ferromagnetic resonance (FMR), it is difficult to access the behavi

Chiral surface spin textures in Cu2OSeO3 unveiled by soft X-ray scattering in specular reflection geometry

Autor: V. Ukleev, C. Luo, R. Abrudan, A. Aqeel, C. H. Back, F. Radu

Publikováno v: Science and Technology of Advanced Materials, Vol 23, Iss 1, Pp 682-690 (2022)

Resonant elastic soft X-ray magnetic scattering (XRMS) is a powerful tool to explore long-periodic spin textures in single crystals. However, due to the limited momentum transfer range imposed by long wavelengths of photons in the soft x-ray region,

Autor: M. Cubukcu, S. Pöllath, S. Tacchi, A. Stacey, E. Darwin, C. W. F. Freeman, C. Barton, B. J. Hickey, C. H. Marrows, G. Carlotti, C. H. Back, O. Kazakova

Publikováno v: Micromachines, Vol 13, Iss 11, p 1911 (2022)

We show that magnetic skyrmions can be stabilised at room temperature in continuous [Ir/Co/Pt]5 multilayers on SiO2/Si substrates without the prior application of electric current or magnetic field. While decreasing the Co thickness, a transition of

Layer specific observation of slow thermal equilibration in ultrathin metallic nanostructures by femtosecond X-ray diffraction

Autor: J. Pudell, A. A. Maznev, M. Herzog, M. Kronseder, C. H. Back, G. Malinowski, A. von Reppert, M. Bargheer

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-7 (2018)

Heat transport in ultrathin metal layers is important for potential applications in optical‐magnetic switching, but difficult to access experimentally. Here, the authors use ultrafast X‐ray diffraction to directly probe and explain unexpected tim

Quantifying the critical thickness of electron hybridization in spintronics materials

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-8 (2017)

Surface versus bulk effects in electronic structure of spintronics materials are crucial to their applications but are yet well understood. Here the authors experimentally determine the critical thickness that defines the crossover of electron hybrid

Robust spin-orbit torque and spin-galvanic effect at the Fe/GaAs (001) interface at room temperature

Autor: L. Chen, M. Decker, M. Kronseder, R. Islinger, M. Gmitra, D. Schuh, D. Bougeard, J. Fabian, D. Weiss, C. H. Back

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)

Interfacial spin-orbit torque allows electrical manipulation of magnetization, but this has been shown mostly in polycrystalline metal bilayers. Here the authors show robust spin-orbit torque in single crystalline Fe/GaAs interface at room temperatur
