Additional Capacitance in YBaCuO Bulk
Yang Yi (Shanghai Institute of Metallurgy,Academia Sinica)
In YBa_2Cu_3O_(7-δ) bulks with comparative high resistance at room temperature,an additional equivalent shunt capacitance about 700-3000 pF and its loss faciorsincoherent with sample size have been measured by Wien's capacitance bridge meth-od at 1 kHz frequency.The existence of this capacitance could be explained by thequasi-two-dimensional conductive planes model.
