The correlation in type-II superconductors between the creep rate S and the Second
Magnetization Peak (SMP) phenomenon which produces an increase in Jc, as a function of …

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 …

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 on magnetic and magnetoresistance measurements in two categories of
superconducting Nb films grown via magnetron sputtering and MgB 2 bulk samples. In the …

The oscillatory dynamics and quasi-static Campbell regime of the vortex lattice (VL) in
twinned YBa 2 Cu 3 O 7 single crystals have been explored at low fields near the peak effect …

We have studied the vortex matter phase diagram in two carbon doped MgB 2− x C x (x=
0.04 and 0.1) single crystals. We have found that, as in pristine MgB 2, the peak effect is also …

We study the vortex phase diagram of the single-layer Bi 2 Sr 2 CuO 6+ δ (Bi2201)
superconductor by means of bulk magnetization measurements on high-quality oxygen …

The vortex matter properties of a Ba1− xKxFe2As2 single crystal (Tc= 38. 2 K) were studied,
by employing both isofield and isothermal ac-susceptibility measurements, χn (f, H0)= χ′ n …

A commercially available powder of MgB2 is used as starting material for the examination of
the influence of the annealing temperature on the properties of this intermediate-Tc …

We report on magnetic measurements as a function of field, temperature and time
(relaxation) in superconducting Nb films of critical temperature Tc= 9.25 K. The magnetic …
