Electrically induced angular momentum flow between separated ferromagnets
Richard Schlitz, Matthias Grammer, Tobias Wimmer +7
Converting angular momentum between different degrees of freedom within a magnetic material results from a dynamic interplay between electrons, magnons and phonons. This interplay…
Impact of magnetic anisotropy on the magnon Hanle effect in -FeO
Monika Scheufele, Janine Gückelhorn, Matthias Opel +5
In easy-plane antiferromagnets, the nature of the elementary excitations of the spin system is captured by the precession of the magnon pseudospin around its equilibrium pseudofiel…
Optimizing the growth conditions of Al mirrors for superconducting nanowire single-photon detectors
R. Flaschmann, C. Schmid, L. Zugliani +9
We investigate the growth conditions for thin (less than 200 nm) sputtered aluminum (Al) films. These coatings are needed for various applications, e.g. for advanced manufacturing…
Site-Selective Enhancement of Superconducting Nanowire Single-Photon Detectors via Local Helium Ion Irradiation
Stefan Strohauer, Fabian Wietschorke, Lucio Zugliani +9
Achieving homogeneous performance metrics between nominally identical pixels is challenging for the operation of arrays of superconducting nanowire single-photon detectors (SNSPDs)…
