Periodic Array of Pinning Sites
Low matching fields

The movie illustrates the low matching fields for a square array of pinning sites. Vortices enter the pinning region at the left and right edges of the sample, increasing the vortex density inside the sample. Circles represent vortices.

The parabolic pins in this sample are in a square array at a density of np = 0.46 (Pinning site density) and are all of strength fp = 0.45 (Pinning site strength) The first two matching fields, along with matching fields of less than one, are shown.
