Point contact spectroscopy is commonly used to investigate electronic properties of superconductors. Here we show that nanometer scale point contacts, which enable to study the superconductor properties locally, can be created by means of the resistive ...

Planar Superconductor-Normal-Superconductor Josephson Junctions in MgB2
Since the discovery of superconductivity in MgB2 considerable progress has been made in determining the physical properties of the material, which are promising for bulk conductors. Tunneling studies show that the material is reasonably isotropic and has

DC‐Driven Fractional Flux Quanta in Two‐Band Superconductors
The dc‐driven distancing of fractional flux quanta is theoretically analyzed for a dual‐band superconductor with a periodic pinning potential. The analysis is based on the dynamical equation of motion for a single composite vortex. The model neglects the phase difference between the condensates and may be applicable to two‐band superconductors with ...

Properties Of MgB2/Ga Composites Prepared By Mechanical Alloying
In this study, we examined the effect of Ga-doping and mechanical alloying in MgB2 on microstructural and phase evolution. A comparison was made between in-situ and ex-situ processed Mg-B-Ga samples.

Increases in the Irreversibility Field and the Upper Critical Field of Bulk MgB2 by ZrB2 Addition
In a study of the influence of ZrB2 additions on the irreversibility field, Birr and the upper critical field Bc2, bulk samples with 7.5 at. % ZrB2 additions were made by a powder milling and compaction technique.

Ambient Condition Superconductivity via Engineered Polaronic Environment
A novel strategy for increasing the critical temperature T c of superconductors is proposed. It involves mating ultrathin layers of superconductors (e.g. MgB2) and metal‐organic framework materials, with a renormalized dielectric response yielding a new system with strengthened Cooper pairing via resonant antishielding.
