Superconducting microwave magnetometer for absolute flux detection
Simon Günzler, Patrick Winkel, Dennis Rieger +5
Superconducting quantum interference devices (SQUIDs) are among the most sensitive detectors for out-of-plane magnetic field components. However, due to their periodic response wit…
Spin polarization and magnetotransport properties of systematically disordered thin films
Kiril Borisov, Jonathan Ehrler, Ciaran Fowley +8
We investigate the evolution of spin polarization, spontaneous Hall angle (SHA), saturation magnetization and Curie temperature of -ordered FeAl thin films under…
The SRG X-ray orbital observatory, its telescopes and first scientific results
R. Sunyaev, V. Arefiev, V. Babyshkin +39
The orbital observatory Spectrum-Roentgen-Gamma (SRG), equipped with the grazing-incidence X-ray telescopes Mikhail Pavlinsky ART-XC and eROSITA, was launched by Roscosmos to the L…
Implementation of a transmon qubit using superconducting granular aluminum
Patrick Winkel, Kiril Borisov, Lukas Grünhaupt +6
The high kinetic inductance offered by granular aluminum (grAl) has recently been employed for linear inductors in superconducting high-impedance qubits and kinetic inductance dete…
New laboratory techniques using heterodyne receivers
Nadine Wehres, Kirill Borisov, Katharina von Schoeler +4
Two laboratory emission spectrometers have been designed and described previously. Here, we present a follow-up study with special focus on absolute intensity calibration of the ne…
Non-degenerate parametric amplifiers based on dispersion engineered Josephson junction arrays
Patrick Winkel, Ivan Takmakov, Dennis Rieger +12
Determining the state of a qubit on a timescale much shorter than its relaxation time is an essential requirement for quantum information processing. With the aid of a new type of…
Onset of phase diffusion in high kinetic inductance granular aluminum micro-SQUIDs
Felix Friedrich, Patrick Winkel, Kiril Borisov +4
Superconducting granular aluminum is attracting increasing interest due to its high kinetic inductance and low dissipation, favoring its use in kinetic inductance particle detector…
Study of the Effect of Annealing on the Properties of Mn2RuxGa Thin Films
K. E. Siewierska, G. Atcheson, K. Borisov +3
The effect of vacuum annealing thin films of the compensated ferrimagnetic half-metal Mn2RuxGa at temperatures from 250 to 400 degree Celsius is investigated. The 39.3 nm films dep…
Magnetocrystalline anisotropy and exchange probed by high-field anomalous Hall effect in fully-compensated half-metallic Mn2RuxGa thin films
Ciarán Fowley, Karsten Rode, Yong-Chang Lau +12
Magnetotransport is investigated in thin films of the half-metallic ferrimagnet MnRuGa in pulsed magnetic fields of up to 58 T. A non-vanishing Hall signal is observed over…
Magneto-optic Kerr effect in a spin-polarized zero-moment ferrimagnet
Karsten Fleischer, Naganivetha Thiyagarajah, Yong-Chang Lau +6
The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetisation of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically…
Proximity-induced superconductivity and quantum interference in topological crystalline insulator SnTe thin film devices
Robin-Pierre Klett, Joachim Schönle, Andreas Becker +12
Topological crystalline insulators represent a new state of matter, in which the electronic transport is governed by mirror-symmetry protected Dirac surface states. Due to the heli…
Exchange coupling of a perpendicular ferromagnet to a half-metallic compensated ferrimagnet via a thin hafnium interlayer
Kiril Borisov, Gwenaël Atcheson, Gavin D'Arcy +3
A thin Hafnium film is shown to act both as an effective diffusion barrier for manganese at a thickness of 0.7 nm, and as an effective exchange coupling layer in a sandwich structu…
Structure, site-specific magnetism and magneto-transport properties of epitaxial D0 MnFeGa thin films
Davide Betto, Yong-Chang Lau, Kiril Borisov +5
Ferrimagnetic MnFeGa thin films have been characterised by X-ray diffraction, SQUID magnetometry, X-ray absorption spectroscopy, X-ray magnetic ci…
