Abstract

We report the phase diagram for magnetic fluxoids in two-dimensional InInOx superconducting films. The films are sputtered directly onto high-Q silicon oscillators. The melting of the vortex lattice is signaled by a peak in the attenuation and a shift of the resonant frequency of the oscillator, caused by the rapid change in mobility of the vortex array. The zero-field limit of the melting temperature can be fitted by the Kosterlitz-Thouless model. However, the magnetic field dependence disagree with the current theoretical picture.
