We report measurements of the electric field vs current density [E(J)] characteristics in the mixed state of amorphous Nb0.7Ge0.3 microbridges. Close to the transition temperature Tc the Larkin-Ovchinnikov theory of nonlinear flux flow and the related instability describes the data quantitatively up to ${\approx}$70% of the upper critical magnetic field Bc2 and over a wide electric-field range. ...
