Abstract

Commensurability effects between the superconducting flux-line lattice and a square lattice (period (Formula presented)) of submicron holes (diameter (Formula presented)) in 1500 Å vanadium films were studied by atomic-force microscopy, dc magnetization, ac susceptibility, magnetoresistivity, and (Formula presented) measurements. Peaks in the susceptibility and critical current at matching fields are found to depend nonlinearly upon the value of external ac field or current, as well as the inferred symmetry of the flux-line lattice.
