✦ Synopsis

It has been shown that Nd 1+x Ba 2-x Cu 3 O 7-x could exhibit a pronounced J c (H) peak effect, which results in an enhancement of the critical current density under the medium range magnetic field. Additions of small quantities of Nd 2 O 3 into Pt-doped YBa 2 Cu 3 O 7-x (Y123) resulted in the formation of nanosized (30-60 nm) secondary phases which are expected to have a significant effect on superconducting properties of melt textured Y123 single crystals. By considering of solidification kinetics, effect of neodymium oxide and platinum addition on processing parameters of melt textured Y123 superconductors are discussed.
