Processing of a TlBa2Ca2Cu3Oy superconducting film by liquid-gas solidification
Abstract
We succeed for the first time in growing a superconducting TlBa2Ca2Cu3Oy film on MgO<100> substrate using a liquid-gas solidification process (LGS). The films are grown in situ; they are deposited by LGS. There is no post-anneal or compensation of Tl applied after the initial deposition. The as-grown film shows a flat and uniform morphology with the c axis perpendicular to the MgO<100>. It exhibits a resistant transition onset of 117 K and zero resistance at 103 K.
