- Title
Deformation-Induced Thermomagnetic Effects in a Twisted Weak-Link-Bearing Superconductor.
- Authors
Sergeenkov, S. A.
- Abstract
Based upon the recently introduced thermophase and piezophase mesoscopic quantum effects in Josephson junctions, several novel phenomena in a twisted superconductor (containing a small annular SIS-type contact) under the influence of a thermal gradient and applied magnetic field are predicted. Namely, we consider a torsional analog of Josephson piezomagnetism (and related magnetomechanical effect), as well as the possible generation of a heat-flux-induced magnetic moment in a weakly coupled superconductor under torsional deformation (analog of Zavaritskii effect) along with the concomitant phenomena of piezothermopower and piezothermal conductivity. The conditions under which the predicted effects can be experimentally measured in conventional superconductors and nanostructure materials with implanted Josephson contacts are discussed. © 2002 MAIK “Nauka / Interperiodica”.
