Real space imaging of metastable flux line lattices in a weakly pinned NbSe2 single crystal (original) (raw)

2014

Abstract

ABSTRACT Using low temperature scanning tunnelling spectroscopy down to 350 mK we study variety of vortex lattice states that emerge in a weakly pinned NbSe2 single crystal. Using small magnetic field pulses, and temperature cycling protocols in magnetic field we access various vortex lattice configurations characterised by different degree of order: Quasi long range ordered states characterised by the absence of topological defects and vortex glass states characterised by the proliferation of dislocations. We explicitly show that the quasi long range ordered state comprises of several metastable states with different "local" configuration of the vortex lattice, consistent with predictions of a Bragg glass.
