| Abstract: | An experimental investigation has been made of the dielectric properties of planar Cu-Cr/Ba0.5Sr0.5TiO3 and YBa2Cu3O7−δ /Ba0.5Sr0.5TiO3 structures in the temperature range 78–300 K. It is shown that the use of YBa2Cu3O7−δ electrodes in Ba0.5Sr0.5TiO3 film structures ensures that there is no dielectric hysteresis in the paraelectric phase. At the same time, the dielectric nonlinearity is preserved and the dielectric losses are reduced. Pis’ma Zh. Tekh. Fiz. 23, 46–52 (August 12, 1997) |
