Abstract

© The American Physical Society. This work was supported by the CICYT Grant No. BMF2001-1419, the ESF Network “Phi-shift,” the project DG236RIC “NDA” and the TRN “DeQUACS.”<br />We have studied the electromagnetic parameters of YBa2Cu3O7 Josephson junctions fabricated on bicrystalline substrates with different angles tilted around the [100] and [001] axis. Changing a technological parameter such as the junction width permits change to the resonant frequency of the barrier cavity. This change in the resonance frequency allows one to determine a frequency dependent dispersion relation of the dielectric constant epsilon(omega). We have explored the proximity to a resonance in the dielectric response and analyzed its resonance frequency and damping constant. In terms of a RLC circuital equivalence additional information on the inductive response is presented as a comparative study of junctions fabricated on substrates with different bicrystalline misorientations.<br />CICYT<br />ESF Network “Phi-shift”<br />Depto. de Estructura de la Materia, Física Térmica y Electrónica<br />Fac. de Ciencias Físicas<br />TRUE<br />pub
