Superconducting magnesium diboride coatings for radio frequency cavities fabricated by hybrid physical-chemical vapor deposition [PDF]
We have investigated the coating of an inner surface of superconducting radio frequency cavities with a magnesium diboride thin film by hybrid physical-chemical vapor deposition (HPCVD). To simulate a 6 GHz rf cavity, a straight stainless steel tube of 1.

Vortex Imaging in the
We report scanning tunneling spectroscopy imaging of the vortex lattice in single crystalline MgB2. By tunneling parallel to the c-axis, a single superconducting gap (Delta = 2.2 meV) associated with the pi-band is observed.

Linking critical temperature with electron localization for cavity-enhanced superconductivity [PDF]
Predicting superconducting properties from first principles—especially in non-equilibrium conditions—is computationally intensive. Here, we propose a more efficient approach by using the electron localization function (ELF) as a proxy for estimating the ...

Synthesis of nanoscale magnesium diboride powder [PDF]
A procedure has been developed for the preparation of small grained magnesium diboride (MgB2) powder by reacting nanometer size boron powder in a magnesium vapor. Plasma synthesized boron powder that had particle sizes ranging from 20 to 300nm was mixed with millimeter size chunks of Mg by rolling stoichiometric amounts of the powders in a sealed ...

Ceramic processing of magnesium diboride
This thesis describes the fabrication and characterization of ex situ magnesium diboride (MgB2) bulk material to study its sintering behaviour. Since the discovery of superconductivity in magnesium diboride in 2001, many research studies have identified the attractive properties of this easy-to-fabricate, low cost superconductor which can attain high ...

Magnesium diboride superconductors for magnet applications
With the discovery of its superconducting properties in 2001, MgB2 is the latest superconductor for use in large scale applications such as superconducting magnets. Compared to other metallic superconductors like Nb-Ti and Nb3Sn, it has the advantage of a higher Tc (40 K), which enables magnets to operate at higher temperatures (» 20 K) and cuts down ...

The pressure dependence of the critical temperature of MgB2 [PDF]
The dependence of the critical temperature Tc on the pressure P in the magnesium diboride MgB2 has been studied in the two-band model. In each band consists of two pairing interaction, electron-phonon interaction and non-electron-phonon interaction ...
