SYNTHESIS OF YNI2B2C THIN-FILMS BY MAGNETRON SPUTTERING

Thin films of YNi2B2C superconductor by the magnetron sputtering techn ique have been synthesized. The YNi2B2C phase was found to crystallize very uniformly after annealing at 1050-degrees-C in vacuum. The struc ture was investigated and the electric and magnetic properties were ch aracterized. The films were c-axis oriented and showed a T(c) onset of approximately 15 K by both magnetization and resistivity measurements . The results of the critical current measurement suggested the existe nce of anisotropies of pinning force and an upper critical field B(c)2 .
