YBa 2 Cu 3 O 7-δ (YBCO) films are prepared on the substrate of single crystal LaAlO 3 (LAO) by using metal trifluoroacetates deposition (TFA-MOD). The phase evolvement, magneto-transport and flux pinning characteristics in MOD - YBCO films are studied. It is revealed that Ba - Cu - O and Y - Cu - O precipitates are formed and can be controlled by optimum crystallization process. The field dependence of Jc ( H // c ) shows that the accommodation field Hacc decreases exponentially with increasing temperature and the power-law relationship holds in the medium fields with an exponent α of about 0.67, nearly independent of temperatures. Compared with the samples grown by pulsed laser deposition, MOD films have larger Hacc at higher temperatures (> 50 K) indicating that the value of the exponent α is affected by the precipitates entrapped in the YBCO matrix.

Magnetic critical current density was measured at various temperatures and fields for SmBa 2 Cu 3 O 7-x single crystal. Pronounced second peaks were observed at intermediate fields and temperatures. Normalized pinning force density [Formula: see text] exhibited a clear scaling law when H was normalized by H max where the pinning force density has the maximum value. This is an indication that a single pinning mechanism exists in the investigated temperature region.
