Abstract
Pinning of flux line lattice has been studied in hydrogenated amorphou s superconducting Re94Cr6 alloys at different hydrogen contents. Resis tivity measurements in magnetic field were made. A change of pinning m echanism was observed from single to collective pinning, depending on the hydrogen content. A sharp peak of the volume pinning force was obs erved in the vicinity of the critical magnetic held, and explained as a result of the abrupt change in the state of the vortex lattice close to the defects.
