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.
