A general phenomenology for phase behavior in the mixed phase of type-II superconductors with weak point pinning disorder is outlined. We propose that the Bragg glass'' phase generically transforms via two separate thermodynamic phase transitions into a disordered liquid on increasing the temperature. The first transition is into a glassy phase, topologically disordered at the largest length scales; current evidence suggests that it lacks the long-ranged phase correlations expected of a…

Order-disorder transitions between glassy phases are common in nature and yet a comprehensive survey on the entailed structural changes is challenging since the constituents are in the micro-scale.

Using neutron scattering to probe the vortex order in superconducting vanadium, an order-disorder transition is uncovered from a quasi-long-range-ordered phase to a vortex glass that is unconnected with peaks observed in critical current.

The vortex lattice in a Type II superconductor provides a versatile model system to investigate the order-disorder transition in a periodic medium in the presence of random pinning, and the existence of a variety of additional non-equilibrium metastable states can be accessed through different thermomagnetic cycling.

Scanning tunnelling spectroscopy in a weakly pinned Co0.0075NbSe2 single crystal shows that the vortex lattice in a 3-dimensional superconductor disorders through successive destruction of positional and orientational order, as the magnetic field is increased across the peak effect.

A metastable homogeneous state exists down to zero temperature in systems of repelling vortices. A zero- fluctuation-temperature'' liquid state therefore serves as a (pseudo) fixed point''
