Nonhomogenous transport current density and voltage distribution in isotropic high Tc superconductors

Transport properties in patterned isotropic high Tc superconducting samples were investigated numerically and experimentally for boundary conditions imposing a nonhomogeneous current flow. Numerical simulations for the voltage distribution were based on a local nonlinear constitutive relation for th...
