High Spin-Wave Propagation Length Consistent with Low Damping in a Metallic Ferromagnet
Luis Flacke, Lukas Liensberger, Matthias Althammer +11
We report ultra-low intrinsic magnetic damping in CoFe heterostructures, reaching the low regime at room temperature. By using a broadband fer…
Exchange-enhanced Ultrastrong Magnon-Magnon Coupling in a Compensated Ferrimagnet
Lukas Liensberger, Akashdeep Kamra, Hannes Maier-Flaig +7
The ultrastrong coupling of (quasi-)particles has gained considerable attention due to its application potential and richness of the underlying physics. Coupling phenomena arising…
Perpendicular magnetic anisotropy in insulating ferrimagnetic gadolinium iron garnet thin films
H. Maier-Flaig, S. Geprägs, Z. Qiu +5
We present experimental control of the magnetic anisotropy in a gadolinium iron garnet (GdIG) thin film from in-plane to perpendicular anisotropy by simply changing the sample temp…
Spin Hall Magnetoresistance Induced by a Non-Equilibrium Proximity Effect
H. Nakayama, M. Althammer, Y. -T. Chen +11
We report anisotropic magnetoresistance in Pt|Y3Fe5O12 bilayers. In spite of Y3Fe5O12 being a very good electrical insulator, the resistance of the Pt layer reflects its magnetizat…
Novel Multifunctional Materials Based on Oxide Thin Films and Artificial Heteroepitaxial Multilayers
Matthias Opel, Stephan Gepraegs, Edwin P. Menzel +14
Transition metal oxides show fascinating physical properties such as high temperature superconductivity, ferro- and antiferromagnetism, ferroelectricity or even multiferroicity. Th…
Giant magnetic anisotropy changes in Sr2CrReO6 thin films on BaTiO3
F. D. Czeschka, S. Gepraegs, M. Opel +2
The integration of ferromagnetic and ferroelectric materials into hybrid heterostructures yields multifunctional systems with improved or novel functionality. We here report on the…
