Bb. Jin et al., The anomalous unloaded quality factor behavior of high T-c superconductingmicrostrip resonator in weak dc magnetic field, J SUPERCOND, 13(1), 2000, pp. 85-88
This paper reports the anomalous behavior of unloaded quality factor (Q(u))
of high T-c superconducting (HTSC) microstrip resonator in weak de magneti
c field (B-dc) The Q(u) behavior increases with the elevated applied B-dc b
ut beyond the certain B-dc value, decreases linearly with B-dc. We speculat
e that this behavior may be caused by edge effect. The behavior is modeled
both by the coupled-grain model accounting for a distribution of the grain
dimension and Coffey-Clem model.
