Abstract
We have investigated the nonlinear flux flow in the mixed state of 2H-NbSe2 superconducting thin crystals stamped on SiO2/Si substrates. The nonlinearity in the flux flow behavior is marked with upward bending and subsequent voltage jump in the current-voltage characteristics. The results were analyzed within the framework of a modified Larkin-Ovchinnikov model, including the estimation of inelastic relaxation time of quasiparticles in the crystal and heat transfer coefficient between the crystal and SiO2/Si substrate. The analysis provides an insight into the quality of acoustic match at the crystal-substrate interface.
