The high‐temperature microwave complex permittivity of YBa 2 Cu 3 O 7‐δ superconductors was characterized using a coaxial probe system designed and built in our laboratory. An anomalous difference in complex permittivity between a green sample and a sintered sample was analyzed with respect to oxygen content being a possible key factor to affect the dielectric properties.
Aral et al. (1995) studied this question.
