Mapping the stray fields of a nanomagnet using spin qubits in SiC
M. Bejarano, F. J. T. Goncalves, M. Hollenbach +7
We report the use of optically addressable spin qubits in SiC to probe the magnetic stray fields generated by a ferromagnetic microstructure lithographically patterned on the surfa…
Bipolar spin Hall nano-oscillators
T. Hache, Y. Li, T. Weinhold +5
We demonstrate a novel type of spin Hall nano-oscillator (SHNO) that allows for efficient tuning of magnetic auto-oscillations over an extended range of gigahertz frequencies, usin…
Free-standing and positionable microwave antenna device for magneto-optical spectroscopy experiments
T. Hache, M. Vaňatka, L. Flajšman +11
Modern spectroscopic techniques for the investigation of magnetization dynamics in micro- and nano- structures or thin films use typically microwave antennas which are directly fab…
Combined frequency and time domain measurements on injection-locked, constriction-based spin Hall nano-oscillators
T. Hache, T. Weinhold, K. Schultheiss +7
We demonstrate a combined frequency and time domain investigation of injection-locked, constriction-based spin Hall nano-oscillators by Brillouin light scattering (BLS) and time-re…
Injection locking of multiple auto-oscillation modes in a tapered nanowire spin Hall oscillator
Kai Wagner, Andrew Smith, Toni Hache +8
Spin Hall oscillators (SHO) are promising candidates for the generation, detection and amplification of high frequency signals, that are tunable through a wide range of operating f…
Excitation of whispering gallery magnons in a magnetic vortex
K. Schultheiss, R. Verba, F. Wehrmann +10
One of the most fascinating topics in current quantum physics are hybridised systems, in which different quantum resonators are strongly coupled. Prominent examples are circular re…
