Abstract

Smectic order has been generated in superconducting Nb films with two-fold symmetry arrays of symmetric pinning centers. Magnetic fields applied perpendicularly to the films develop a vortex matter smectic phase that is easily detected when the vortices are commensurate with the pinning center array. The smectic phase can be turned on and off with external parameters.
