During the last two decades, vortex structural transitions in type-II superconductors have
been the subject of a considerable amount of theoretical and experimental studies. This …

Vortex matter in type-II superconductors is a model complex system belonging to the vast
ensemble of disordered elastic media. In all these systems, depinning occurs when an …

Order-disorder transitions take place in many physical systems, but observing them in detail
in real materials is difficult. In two-or quasi-two-dimensional systems, the transition has been …

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

Adding impurities or defects destroys crystalline order. Occasionally, however, extraordinary
behaviour emerges that cannot be explained by perturbing the ordered state. One example …

The peak effect (PE) in the critical current density of type II superconductors has been
related to an order-disorder transition in the vortex lattice (VL), but its underlying physics …

We report a pronounced peak effect in the magnetization of Co x NbSe 2 single crystals with
critical temperatures T c ranging between 7.1 and 5.0 K, and Mn x NbSe 2 single crystals …

A gel consists of a network of particles or molecules formed for example using the sol-gel
process, by which a solution transforms into a porous solid. Particles or molecules in a gel …

We present a systematic study of the topology of the vortex solid phase in superconducting B
i 2 S r 2 C a C u 2 O 8 samples with low doses of columnar defects. A new state of vortex …

We study a simple model for the depinning and driven steady-state phases of a solid tuned
across a polymorphic phase transition between ground states of triangular and square …
