摘要

We have examined the correlation between the critical current density (J(c)) and the surface resistance (R-s) of an YBa2Cu3O7-delta (YBCO) thin film. YBCO films were prepared in an inductively coupled plasma sputtering system on MgO and BSO/MgO substrates. BaSnO3 (BSO) was used as a buffer material for the MgO substrates. J(c) was determined by magnetic measurements, and R-s was measured using a sapphire rod resonator method, The correlation of critical current and surface resistance has been reported previously, however. there is few researches in which a systematic correlation of R-s and J(c) using the same sample has been done. To begin with, we measured R-s by the dielectric resonator method, and next, J(c) was measured using the magnetic field method, As a result, it was proven that there was a strong correlation between R-s and J(c). We found that the relationship between J(c) and R-s (at 22 GHz) could be expressed by the following equation, R-s = 2.0 x 10(7) J(c)(-1), where the unit of R-s is the ohm, and the unit of J(c) is A/m(2). It was found that the relation was applicable in a wide temperature range under T,. The value of the surface resistance can be estimated. if an accurate critical current is obtained.
