Performance of a low-parasitic frequency-domain multiplexing readout
A. E. Lowitz, A. N. Bender, P. Barry +14
Frequency-domain multiplexing is a readout technique for transition edge sensor bolometer arrays used on modern CMB experiments, including the SPT-3G receiver. Here, we present des…
Superconducting nanowires as high-rate photon detectors in strong magnetic fields
T. Polakovic, W. R. Armstrong, V. Yefremenko +5
Superconducting nanowire single photon detectors are capable of single-photon detection across a large spectral range, with near unity detection efficiency, picosecond timing jitte…
Evidence of Vortex Jamming in Abrikosov Vortex Flux Flow Regime
G. Karapetrov, V. Yefremenko, G. Mihajlović +4
We report on dynamics of non-local Abrikosov vortex flow in mesoscopic superconducting Nb channels. Magnetic field dependence of the non-local voltage induced by the flux flow show…
Surface spin flip probability of mesoscopic Ag wires
G. Mihajlovic, J. E. Pearson, S. D. Bader +1
Spin relaxation in mesoscopic Ag wires in the diffusive transport regime is studied via nonlocal spin valve and Hanle effect measurements performed on permalloy/Ag lateral spin val…
Imaging of lateral spin valves with soft X-ray microscopy
O. Mosendz, G. Mihailovic, J. E. Pearson +4
We investigated Co/Cu lateral spin valves by means of high-resolution transmission soft x-ray microscopy with magnetic contrast that utilizes x-ray magnetic circular dichroism (XMC…
Low Temperature Thermal Transport in Partially Perforated Silicon Nitride Membranes
V. Yefremenko, G. Wang, V. Novosad +10
The thermal transport in partially trenched silicon nitride membranes has been studied in the temperature range from 0.3 to 0.6 K, with the transition edge sensor (TES), the sole s…
