Quasiparticle-injection effect in YBa2Cu3Ox-based planar structures [PDF]

open access: yes, 1993
The supercurrent IS of a YBCO bridge can be modulated by the quasiparticle-injection current IG from YBCO/Au or YBCO/PBCO/Au junctions. The behavior of these structures is determined by two effects: 1) summation of the currents IS and IG in the YBCO ...
