Abstract
We report on measurements of a mode-locking resonance in amorphous Mo x Ge 1− x films at different temperatures T down to 0.8 K, which is well below the superconducting transition (6 K). 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.
