摘要：

The influence of rare earth (RE) ion size on critical current density (J(c)) in epitaxial films of superconducting REBa2CuO7-x was studied, where RE is the mixture of two or three rare earth ions. No systematic dependence of Jc on RE ion size was found. However, strongly enhanced critical current densities (J(c)'s) were found for the composition Y2/3SM1/3Ba2Cu3O7-x (YSmBCO). In similar to1-mum-thick films, J(c)'s as high as 4.7X 10(6) A cm(-2) (7.5.5 K, 0 T) and 1 X 10(4) A cm(-2) (75.5 K, 5 T) were obtained on single crystals and 6 X 104 A cm(-2) (75.5 K, 5 T) on buffered metal. The values are up to a factor of 3 higher than for comparative YBCO samples. (C) 2005 American Institute of Physics.
