We report measurements of a dynamic instability in the moving vortex system of Ta/Ge-based thin films and multilayers. The instability results from a nonequilibrium distribution of quasiparticles induced by motion of the vortex cores, as described theoretically by Larkin and Ovchinnikov in the regime where there is no pinning. For the Ta/Ge system, where the critical vortex velocity is relatively small, we observe the instability in cases where either the viscosity or pinning dominate thedoi:10.1103/physrevb.62.12468 fatcat:sdotvm7u3fdabh44dilaui37wu
