Electrostatic Stabilization of Near-Surface Quantum Sensors via Dielectric Interface Engineering
Atharva Paranjape, Kathrin Küster, Olga Shevstova +6
Control of charge-state stability in near-surface quantum defects is critical for nanoscale sensing, yet remains particularly challenging under ultra-high vacuum (UHV), where surfa…
Nanoscale Mapping of Magnetic Auto-oscillations with a single Spin Sensor
Toni Hache, Anshu Anshu, Tetyana Shalomayeva +4
Magnetic auto-oscillations are damping-compensated magnetization precessions. They can be generated in spin Hall nano-oscillators (SHNO) among others. Current research on these dev…
Control of 4-magnon-scattering in a magnonic waveguide by pure spin current
Toni Hache, Lukas Koerber, Tobias Hula +6
We use a pure spin current originating from the spin Hall effect to generate a spin-orbit torque (SOT) strongly reducing the effective damping in an adjacent ferromagnet. Due to ad…
Nonlinear magnon control of atomic spin defects in scalable quantum devices
Mauricio Bejarano, Francisco J. T. Goncalves, Toni Hache +10
Ongoing efforts in quantum engineering have recently focused on integrating magnonics into hybrid quantum architectures for novel functionalities. While hybrid magnon-quantum spin…
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…
