摘要：

Dielectric properties of 400-600 nm thick epitaxial layers of SrTiO3 and Ba0.9Sr0.1TiO3, inserted between YBa2Cu3O7-delta or NdBa2Cu3O7-delta electrodes, were investigated as functions of temperature and electric field. The electric field response of the dielectric permittivity of the ferro electric layer correlated with the Curie point and was considerably higher with Nd based than with Y based superconducting electrodes. Insertion of thin buffer layers improved the tunability and decreased the microwave losses of the Ba doped dielectric.
