| Abstract(in English) | We intend to develop a high-T_C superconductor (HTSC) /ferromagnetic insulator EuO/HTSC Josephson junction. Ferromagnetic Curie temperature of EuO is 69 K. It is expected that the effect of ferromagnetism on junction characteristic is investigated as considering the transition from paramagnetism to ferromagnetism of barrier layer below T_C. As a first step to develop such a junction, we grew EuO film on MgO substrate, which has same structure as EuO, and on SrTiO_3 substrate, which structure is a base of HTSC layered structure. EuO films epitaxially grew directly on MgO substrate, and on SrTiO_3 substrate with BaO buffer layer. Such films had magnetic properties same as bulk. |
