High performance magnetic field sensor based on Superconducting Quantum Interference Filters
P. Caputo, J. Oppenlaender, Ch. Haeussler +4
We have developed an absolute magnetic field sensor using Superconducting Quantum Interference Filter (SQIF) made of high-T_c grain boundary Josephson junctions. The device shows t…
Influence of Fermi surface topology on the quasiparticle spectrum in the vortex state
S. Graser, T. Dahm, N. Schopohl
We study the influence of Fermi surface topology on the quasiparticle density of states in the vortex state of type II superconductors. We observe that the field dependence and the…
Fermi surface topology and vortex state in MgB2
T. Dahm, S. Graser, N. Schopohl
Based on a detailed modeling of the Fermi surface topology of MgB2 we calculated the anisotropy of the upper critical field Bc2 within the two gap model. The sigma-band is modeled…
Effects of magnetic field on two-dimensional Superconducting Quantum Interference Filters
J. Oppenlaender, P. Caputo, Ch. Haeussler +4
We present an experimental study of two-dimensional superconducting quantum interference filters (2D-SQIFs) in the presence of a magnetic field B. The dependences of the dc voltage…
Electromagnetomotive force fields in noninertial reference frames and accelerated superconducting quantum interferometers
Uwe R. Fischer, Christoph Haeussler, Joerg Oppenlaender +1
We discuss the prospects of detecting with high precision the force fields related to noninertiality in superconducting circuits. Special emphasis is laid on the perfectly conducti…
Short wavelength spectrum and Hamiltonian stability of vortex rings
Uwe R. Fischer, Nils Schopohl
We compare dynamical and energetical stability criteria for vortex rings. It is argued that vortex rings will be intrinsically unstable against perturbations with short wavelengths…
