Effect of magnetic field on the temperature gradient in Y1Ba2Cu3O7 − δ + Eu1Ba2Cu3O7 − δ rods

A method for growing Y1Ba2Cu3O7 − δ + Eu1Ba2Cu3O7 − δ (YBCO-EBCO) high-temperature superconductor rods is described. The temperature dependences of the resistance of rods in a magnetic field of B = 0.6 T and in the absence of the field (B = 0 T) are presented. The current-voltage characteristics of YBCO-EBCO rods have been measured at liquid nitrogen temperature have been measured in the absence and presence of a magnetic field. It is shown that the magnetic field significantly decreases the temperature gradient arising when the rod leaves the superconducting state.
