Magnesium Diboride Superconducting Devices and Circuits
While magnesium diboride (MgB2) was first synthesized in the 1950s, MgB2’s superconductive properties were not discovered until 2001. It has the highest superconducting transition temperature of all the metallic superconductors at ~39 K at atmospheric pressure. MgB2 is also unique in that it has a …

Enhancement of superconductivity in Magnesium Diboride nano-structures
For many years scientists have tried different strategies to improve superconductivity. The recent development in the growth of thin films and grains at the nanoscale has allowed to measure in certain materials critical temperatures that differ from the bulk values. At the same time these results …

Part I. Synthesis of Metal Hydroborates as Potential Chemical Vapor Deposition Precursors. Part II. Chemical Vapor Deposition of Titanium-Doped Magnesium Diboride Thin Films
The first low-temperature chemical vapor depositions of doped MgB 2 phases have been achieved by passing the precursor Mg(H3BNMe 2BH3)2 over a surface in the presence of a catalyst that accelerates the rate of the CVD growth reaction. Transition metal hydroborates can serve as effective catalysts, …

Synthetic studies of sodium aminodiboranate salts with electronwithdrawing substituents
Magnesium diboride, MgB2, has the highest superconducting critical temperature of all traditional superconductors and is being considered for the fabrication of superconducting integrated circuits that can operate at higher temperatures than analogous niobium alloy circuits. A significant barrier …

A persistent-mode MgB₂ 0.5-T/240-mm solid-nitrogen-cooled magnet for MRI
… 2001, a new high-temperature superconductor of magnesium diboride (MgB₂) with a critical temperature of 39 K has spurred intensive R&D effort. A combination of high critical temperature, low manufacturing cost, and good in-field performance makes it viable competitor to NbTi and the basis for …

Advanced Numerical Modelling of Bulk Superconductor Magnetisation
… at approximately 90 K or higher. Magnesium diboride (MgB<sub>2</sub>) is another promising type-II superconductor, which exhibits superconductivity below 39 K. Despite the extensive research into fabricating and using bulk superconductors as trapped field magnets, magnetising them …
