TL;DR: Strong granularity-correlated and intragrain modulations of the superconducting order parameter are demonstrated in heavily boron-doped diamond, revealing that local Cooper pairing sets in prior to the global phase coherence.

TL;DR: In this paper, the morphology of magnetic flux avalanches with engineered periodic pinning centers (antidots) has been investigated, and it was shown that in a superconductor with relatively weak random pinning, the morphology can be fully controlled by proper combinations of lattice symmetry and antidot geometry.

TL;DR: In this paper, the grain size dependence of the superconducting transition, the normal state resistivity, and the insulating behavior at high magnetic fields is studied on a series of boron-doped nanocrystalline diamond (B:NCD) thin films with different grain sizes.

TL;DR: In this paper, a scanning tunneling microscopy investigation of lithographically defined superconducting nanosquares is reported, which reveals the spatial evolution of both the superconding condensate and the screening currents as a function of the applied magnetic field.

TL;DR: In this article, the Ginzburg-Landau approach is used to analyze vortex states and vortex dynamics in type-I superconductor films with a thickness gradient in one direction, and the results of the simulations imply that at moderate external current densities a regime is possible where the winding number of giant vortices, formed as a result of vortex coalescence, takes preferentially (or even exclusively) the values given by positive integer powers of two.
