摘要：
We study the static and dynamic properties of vortices in the vortex solid phase of a thick amorphous MoxGe1-x film with Corbino-disk (CD) and strip-like contact geometries. For the strip-like geometry the peak effect (PE) of the critical currently with magnetic field is clearly visible for all the temperatures studied and large voltage noise originating from current-driven vortices appears in the field region just prior to a peak field where 1, takes a peak. For the CD geometry we observe essentially the same phenomena, indicating that the edge effects are not important for the static or dynamic properties of vortices.
