Effect of praseodymium substitution on the growth and properties of Y1-xPrxBa2Cu3O7-δ (0<x<0.4) single crystals
Description
In the present paper, a modified self-flux technique has been successfully employed for the growth of pure and praseodymium substituted (partially) large single crystals of high temperature superconducting Y1-xPrxBa2Cu3O7-δ (x=0.0, 0.2, 0.4). Typical sizes of the platy and bulky crystals of pure YBCO(123) material are ∼ 2x2x0.1 mm3 and 4x1x1 mm3, respectively. In case of Pr substitution, the typical sizes of platy and bulky crystals of Y0.8Pr0.2Ba2Cu3O7-δ and Y0.6Pr0.4Ba2Cu3O7-δ materials are ∼ 2x3x0.1 mm3 and 5x1x1 mm3 and ∼ 1x1.5x0.1 mm3 and 7x0.2x0.1 mm3, respectively. The morphology and growth habit of the as-grown single crystals and the critical transition temperature (Tc) of the oxygenated crystals were found to depend on the Pr content.
