We report on measurements of a mode-locking resonance in amorphous Mo x Ge 1−x films at different temperatures T down to 0.8K, which is well below the superconducting transition (6K). We observe dynamic ordering of driven vortex matter for all the temperatures studied. As the field exceeds a certain critical field B c,dyn at fixed T, moving vortices do not exhibit dynamic ordering. At high T, this field B c,dyn (T), so-called dynamic melting, nearly coincides with a characteristic field B c (T) where the linear resistivity vanishes. At low T, however, B c,dyn (T) is significantly suppressed compared to B c (T), suggesting intrinsic quantum melting in the absence of pinning.
