摘要

Liquid phase epitaxy (LPE) of REBa₂Cu₃O_7-δ on lattice mismatched substrates requires high supersaturation. However, the solubility of RE's in the fluxes used for growing REBCO is not widely known. In order to precisely control the supersaturation during growth, the solubility of RE's in the Ba:Cu=2:5 solution were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES). Mixing of the RE's in the solution has led to a large increase in the overall RE solubility and, therefore, increase of the growth rate and homogeneity of REBCO thick films grown by LPE. Films of mixed RE's with excellent in-plane c-texture and 100% density, have been grown on LaAlO₃, NdGaO₃, SrTiO₃ YSZ, MgO and Ni/NiO substrates at a mean rate of 1 to 2 μm/min. T_c's of 91 K have been achieved and J_c's over 6×10⁵ A/cm² at 77 K.
