Crystal growth and phase relation of Sm1+xBa2-xCu3Oz

Using the top-seeded solution-growth method, Sm1+xBa2-xCu3Oz (SmBCOss) single crystals and thick films were grown in different solvents. Inductively coupled plasma compositional analysis was performed to both Ba-Cu-O solvents and SmBCOss solid solutions. The results indicate that a nearly stoichiometric SmBa2Cu3Oz phase with high critical transition temperature value, is controllable in a wide range of the thermodynamic parameters. The phase relation of the Sm-Ba-Cu-O system was discussed in comparison with other RE-Ba-Cu-O systems (RE=Y and Nd)
