Title Anisotropic response of the moving vortex lattice in superconducting Mo(1−x)Gex amorphous films Type Journal Article
Year (up) 2012 Publication Physica C: Superconductivity Abbreviated Journal
Volume 474 Issue Pages 34-37
Keywords Superconductivity; 2D systems; Transverse critical current; Anisotropic behavior
Abstract We have performed magnetic susceptibility measurements in Mo(1−x)Gex 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 current–temperature 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.
