Resumen:
We have performed magnetic susceptibility measurements in Mo1xGex amorphous thin films biased
with an electrical current using anisotropic coils. We tested the symmetry of the vortex response changing
the relative orientation between the bias current and the susceptibility coils. We found a region in the
DC currenttemperature phase diagram where the dynamical vortex structures behave anisotropically. In
this region the shielding capability of the superconducting currents measured by the susceptibility coils
is less effective along the direction of vortex motion compared to the transverse direction. This anisotropic
response is found in the same region where the peak effect in the critical current is developed.
On rising temperature the isotropic behavior is recovered
