Abstract

PrBa₂Cu₃O_7-δ/YBa₂Cu ₃O_7-δ (Pr123/Y123) and PrBa₂Cu₃O_7-δ/NdBa₂Cu ₃O_7-δ (Pr123/Nd123) epitaxially grown crystals were fabricated by Liquid Phase Epitaxy (LPE) and the interface structures were investigated by cross-sectional high-resolution electron microscopy (HREM). In the case of Pr123/Y123, crystals were grown on the (001)_Y123 surface of a Y123 substrate, and in the case of Pr123/Nd123, crystals were grown on the (010)_Nd123 surface of a Nd123 substrate. For Pr123/Y123 and Pr123/Nd123, misfit dislocation spacings of 31 nm and 0.7 mm resulted from the lattice mismatch of a-axis were observed, respectively, and no interdiffusion layer was detected within the region of 10 nm apart from the growth interface. The misfit dislocation at the interface was introduced so as to completely release the elastic strains.
