Superconductivity (S) and ferromagnetism (F) are competing phases whose coexistence is unlikely to occur. Exceptions require a non−uniform profile both for the pairing and the magnetization, as in the case of the FFLO state ...

When the applied magnetic field is higher than the lower critical field but below the upper critical field, a type-II superconductor allows magnetic flux to penetrate it in the form of vortices, a tiny normal area surrounded ...

The aim of the OPERA experiment is to provide a “smoking-gun” proof of neutrino oscillations, through the detection of the appearance signal of ντ’s in an initially pure νμ beam. The beam is produced at CERN, 732 Km far ...

Traffic acoustical noise is one of the most important component of the urban environmental pollution in densely populated areas all over the world. A very recent ACI-Censis study [1] on Italian urban areas shows that car ...

Since their discovery, graphene and carbon nanotubes have been playing an important role in nanoscience and nanotechnology thanks to their extraordinary physical and chemical properties. With silicon-based electronics ...

In the framework of the Ginzburg-Landau (G-L) theory [1], conventional superconductors are classified in type I and type II, based on the value the G-L parameter... [edited by Author]

In this works we fabricated four graphene/silicon heterojunctions, which differ for structure and substrate type, and performed electrical and optical characterization. The first device was realized by depositing a layer ...
