Y-system coated conductor on metal substrate by LPE method

Utiligation of MgO as a buffer layer for LPE(Liquid Phase Epitaxy) growth o f YBa2Cu3Oy(Y123) was investigated. In order to investigate the reaction, t he tapes with MgO layers were dipped into the melt of two different composi tions. The tape was completely dissolved into the melt without addition of MgO. However, the tape survived in the MgO-saturated solution. The modified LPE process was developed which is the Y123 LPE growth using the Y123 laye r saturated with MgO as the second buffer layer to prevent dissolution of t he first MgO buffer layer into the melt.
