摘要：

YBa2Cu3O7-x (YBCO) films of 110 nm thickness were prepared on LaAlO3 (LAO) substrates via the solgel method. Subsequently, about 400 nm thick Ba0.09Sr0.91 TiO3 (BST) films were epitaxially grown on the YBCO and LNO films surface; the BST films exhibited a strong c- axis orientation. The dielectric adjustability and relative dielectric constant was investigated in the range of 300-83 K. Results indicate that the tunability of the Ba0.09Sr0.91TiO3/YBa2Cu3O7-x (BST/YBCO) displayed an increase relative to c-axis-oriented BST on LaNiO3 (LNO). The tunability was further enhanced as the operating temperature decreased, yet the loss tangent (tan delta) decreased. The tunability and the tan delta at 100 kHz and 83 K were 58% and 0.029, respectively. (C) 2016 Elsevier B.V. All rights reserved.
