We have studied the field-induced pinning effect of Nd 1 + x Ba 2 − x Cu 3 O 7 − δ single crystals grown by the TSFZ method using feed rods of Nd 1 + α Ba 2 − α Cu 3 O 7 − δ ( α = 0 and 0.1). The ICP measurements reveal that Nd, Ba and C

We have investigated the pseudo-binary phase diagrams between NdBa2Cu3O7-δ (Nd123) and several Ba–Cu–O compositions in air and reduced oxygen atmosphere by DTA, quenching, and X-ray powder diffraction measurements. We found that in air the wider
