Summary:

Magnetic relaxation has been studied for Y₁Ba₂Cu₄O₈ in order to look for changes in the relaxation rates that arise because different pinning mechanisms dominate in different magnetic field regimes. In the low field regime where the Bean-Livingston surface barrier dominates, the vortices exit on a filed decreasing branch with a relaxation rate about ten times faster than they enter on a corresponding field increasing branch. In high magnetic fields where bulk pinning dominates, the relaxation rates for field increasing and field increasing and field decreasing are essentially the same.
