Abstract

We are investigating epitaxially grown YBa$_2Cu_3O_x$(123) on MgO single crystal by partial melting process for high power application. After fabricating of BaCuO$_2$(011), Y$_2BaCuO_5$(211) powder, we made YBa$_2Cu_3O_x$(123) Paste with just mixing of (211), (011) and CuO(001) powders. Screen printing method was used to coat YBa$_2Cu_3O_x$(123) paste on MgO single crystal. To reduce the reaction in low temperature, rapid heating was conducted at partial melting temperature. The film was analysed with the difference of cooling-rate, thickness, reaction temperature by XRD, SEM, in-plane alignment, out-of-plane alignment, temperature-resistivity characteristics.
