Instabilities and Disorder-Driven First-Order Transition of the Vortex Lattice
Instabilities and Disorder-Driven First-Order Transition of the Vortex Lattice
Transport studies in a Corbino disk suggest that the Bragg glass phase undergoes a first-order transition into a disordered solid. This transition shows sharp reentrant behavior at low fields. In contrast, in the conventional strip configuration, the phase transition is obscured by the injection of the disordered vortices through the …
