Magneto-optical evidence for single-crystal-like magnetic switching of epitaxial antiferromagnetic LaFeO3 films
A. Rieche, W. Hoppe, C. Körner +11
Strained epitaxial films of the antiferromagnetic orthoferrite LaFeO3 offer a promising platform for antiferromagnetic spintronics, yet their magnetic switching behavior and domain…
Femtosecond signatures of optically induced magnons before ultrafast demagnetization
Reza Rouzegar, Oliver Franke, Gal Lemut +8
Optically induced demagnetization of 3d metallic ferromagnets proceeds as fast as ~100 fs and is a crucial prerequisite for spintronic applications, such as ultrafast magnetization…
Observation of Ultrafast Coherent and Incoherent Spin Torques via Terahertz Spin-Hall Magnetoresistance
P. Kubaščík, R. Schlitz, O. Gueckstock +19
Spin Hall magnetoresistance (SMR) is a cornerstone effect in spintronics, enabling the electrical readout of magnetic states through spin-orbit coupling at interfaces. Despite its…
Ultrafast electron heating as the dominant driving force of photoinduced terahertz spin currents
Reza Rouzegar, Pilar Jimenez-Cavero, Oliver Gueckstock +9
Ultrafast spintronics strongly relies on the generation, transport, manipulation and detection of terahertz spin currents (TSCs). In F|HM stacks consisting of a ferromagnetic layer…
Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
Switching of magnetic domains in a noncollinear antiferromagnet at the nanoscale
Atul Pandey, Prajwal Rigvedi, Edouard Lesne +8
Antiferromagnets that display very small stray magnetic field are ideal for spintronic applications. Of particular interest are non-collinear, chiral antiferromagnets of the type M…
Anomalous Nernst effect based near field imaging of magnetic nanostructures
Atul Pandey, Jitul Deka, Jiho Yoon +5
The anomalous Nernst effect (ANE) gives rise to an electrical response transverse to the magnetization and an applied temperature gradient in a magnetic metal. A nanoscale temperat…
Laser patterning of magnonic structure via local crystallization of Yittrium Iron Garnet
A. Del Giacco, F. Maspero, V. Levati +15
The fabrication and integration of high-quality structures of Yttrium Iron Garnet (YIG) is critical for magnonics.Films with excellent properties are obtained only on single crysta…
Accessing ultrafast spin-transport dynamics in copper using broadband terahertz spectroscopy
Jiří Jechumtál, Reza Rouzegar, Oliver Gueckstock +10
We study the spatiotemporal dynamics of ultrafast electron spin transport across nanometer-thick copper layers using broadband terahertz spectroscopy. Our analysis of temporal dela…
Integration and characterization of micron-sized YIG structures with very low Gilbert damping on arbitrary substrates
P. Trempler, R. Dreyer, P. Geyer +3
We present a novel process that allows the transfer of monocrystalline yttrium-iron-garnet microstructures onto virtually any kind of substrate. The process is based on a recently…
Monocrystalline free standing 3D yttrium iron garnet magnon nano resonators
F. Heyroth, C. Hauser, P. Trempler +6
Nano resonators in which mechanical vibrations and spin waves can be coupled are an intriguing concept that can be used in quantum information processing to transfer information be…
Composition-tuned magneto-optical Kerr effect in L10-MnxGa films with giant perpendicular anisotropy
L. J. Zhu, L. Brandt, J. H. Zhao +1
We report the large polar magnetooptical Kerr effect in L10-MnxGa epitaxial films with giant perpendicular magnetic anisotropy in a wide composition range. The Kerr rotation was en…
