Keywords:superconductor, vortex, superconducting resonator

Manipulating the resonance frequency,f0, of a superconducting resonator is important for various kinds of applications. Though there are several attempts to control f0 by either introducing current, I, or magnetic field, H, no one tried to apply both of them. Hence, we measured resonance characteristics under I and H. We will give a presentation about the relationship between the resonance characteristics and the configuration of vortices.
