Spin cat states in a ferromagnetic insulator
Sanchar Sharma, Victor A. S. V. Bittencourt, Alexy D. Karenowska +1
Generating non-classical states in macroscopic systems is a long standing challenge. A promising platform in the context of this quest are novel hybrid systems based on magnetic di…
Microwave magnon damping in YIG films at millikelvin temperatures
Sandoko Kosen, Arjan F. van Loo, Dmytro A. Bozhko +2
Magnon systems used in quantum devices require low damping if coherence is to be maintained. The ferrimagnetic electrical insulator yttrium iron garnet (YIG) has low magnon damping…
Measurement of a Magnonic Crystal at Millikelvin Temperatures
S. Kosen, R. G. E. Morris, A. F. van Loo +1
Hybrid systems combining magnons and superconducting quantum circuits have attracted increasing interest in recent years. Magnonic crystals (MCs) are one of the building blocks of…
Inductive detection of field-like and damping-like AC inverse spin-orbit torques in ferromagnet/normal metal bilayers
Andrew J. Berger, Eric R. J. Edwards, Hans T. Nembach +3
Functional spintronic devices rely on spin-charge interconversion effects, such as the reciprocal processes of electric field-driven spin torque and magnetization dynamics-driven s…
Strong coupling of magnons in a YIG sphere to photons in a planar superconducting resonator in the quantum limit
R. G. E. Morris, A. F. van Loo, S. Kosen +1
We report measurements of a superconducting coplanar waveguide resonator (CPWR) coupled to a sphere of yttrium-iron garnet. The non-uniform CPWR field allows us to excite various m…
Time-resolved measurements of surface spin-wave pulses at millikelvin temperatures
A. F. van Loo, R. G. E. Morris, A. D. Karenowska
In this work, we experimentally investigate the propagation of pulsed magnetostatic surface spin-wave (magnon) signals in an yttrium iron garnet (YIG) waveguide at millikelvin temp…
Excitation and detection of propagating spin waves at the single magnon level
Alexy D. Karenowska, Andrew D. Patterson, Michael J. Peterer +2
Ferro- and ferrimagnets play host to small-signal, microwave-frequency magnetic excitations called spin waves, the quanta of which are known as magnons. Over the last decade, the f…
Magnon-phonon coupling unmasked: a direct measurement of magnon temperature
Milan Agrawal, Vitaliy I. Vasyuchka, Alexander A. Serga +3
Thermoelectric phenomena in magnetic materials present tantalizing possibilities for manipulating spin-information using heat in future 'spin caloritronic' devices. Key to unraveli…
Oscillatory Energy Exchange Between Waves Coupled by a Dynamic Artificial Crystal
Alexy D. Karenowska, Vasil S. Tiberkevich, Andrii V. Chumak +4
We describe a general mechanism of controllable energy exchange between waves propagating in a dynamic artificial crystal. We show that if a spatial periodicity is temporarily impo…
Magnonic crystal based forced dominant wavenumber selection in a spin-wave active ring
A. D. Karenowska, A. V. Chumak, A. A. Serga +2
Spontaneous excitation of the dominant mode in a spin-wave active ring -- a self-exciting positive-feedback system incorporating a spin-wave transmission structure -- occurs at a c…
