Magneto-resistances of the coated conductors fabricated on tilted single-crystal Ni substrates

Abstract

The magneto-resistances of coated conductors fabricated on tilted single-crystal Ni substrates were measured under various magnetic fields. The activation energies of vortices were estimated from these results. For the currents flowing in the rolling direction, the activation energies were similar to those of c-axis normal Y1Ba2Cu3O7-delta films on SrTiO3 single crystals and were slightly larger than those of the RABiTS coated conductors. For the currents flowing in the transverse direction, the magneto-resistances show double transitions in temperature with much smaller activation energies.
