Dynamical effects of an unconventional current-phase relation in YBCO dc-SQUIDs
arXiv:cond-mat/0303144 · doi:10.1103/PhysRevLett.90.117002
Abstract
The predominant d-wave pairing symmetry in high temperature superconductors allows for a variety of current-phase relations in Josephson junctions, which is to a certain degree fabrication controlled. In this letter we report on direct experimental observations of the effects of a non-sinusoidal current-phase dependence in YBCO dc-SQUIDs, which agree with the theoretical description of the system.
