SUPERCONDUCTING PROPERTIES OF ND-BA-CU-O THICK-FILMS PREPARED BY LIQUID-PHASE EPITAXIAL-GROWTH

C -axis oriented Nd1+xBa2-xCu3Oy thick films were grown by the liquid phase epitaxy (LPE) technique onto MgO (100) single crystal substrates in Ar gas atmosphere containing 0.5 at,% O-2, The superconducting tra nsition temperature T-c was very broad, when the film thickness was 10 mu m but became very sharp when it was increased to 100 mu m, The T-c value for the 100 mu m thick film could be increased up to 92 K by po stannealing at 300 degrees C for 336 hrs in O-2 atmosphere. Moreover, the peak effect, which is characterized by an increase in magnetizatio n with increasing magnetic Field up to 15000 G at 50 K, was observed i n the 100 mu m thick film, A substantial improvement in the supercondu cting properties when the film thickness is increased to 100 mu m, can be attributed to the stable persistence of the steady state growth mo de instead of the transient mode responsible for the first 10 mu m thi ck deposition.
