Investigations of MgB2/MgO and MgB2/AlN heterostructures for Josephson Devices
2005We report structural and transport proprieties of MgB2/MgO and MgB2/AlN multilayers for MgB2 Josephson junctions. The MgB2, layers were grown by,hybrid physical chemical vapor deposition (HPCVD). The epitaxial MgB2/MgO/MgB2 trilayers were grown in situ in the HPCVD system.

Die Suche nach neuen Supraleitern ging auch nach der Entdeckung der Kuprat-Supraleiter weiter. Wir wollen kurz die wichtigsten Entwicklungen schildern. 2001 berichteten Jun Akimitsu und Mitarbeiter aus Tokyo die Entdeckung von Supraleitung in der Verbindung Magnesiumdiborid (MgB2) mit der kritischen Temperatur TC = 39 K.

Properties of ex-situ MgB2 bulk samples prepared by uniaxial hot pressing and spark plasma sintering
Physica C: Superconductivity and its Applications, 2018The effect of compaction of ex-situ MgB2-powder, i.e. cold and hot uniaxial pressing, Spark Plasma Sintering (SPS) and of a post annealing on microstructure and superconducting properties of ex-situ bulk samples is studied.

The surprising superconductor: MgB2
JOM, 2001For the past decade and a half, scientists have been happily developing a new picture of superconductivity based on the rich phenomena found in the copper-oxide compounds. These superconductors define fascinating new directions: high transition temperatures, weakly coupled layers, exotic states of vortex matter, pseudogaps, stripes, and applications in

Abstract The problems in MgB 2 crystal growth are discussed on the basis of the chemical and thermodynamic information about Mg–B system. After comparing and analyzing the reported crystal growth methods, a novel technique for reproducible crystal growth of MgB 2 at a high pressure in Mg–B–N system is presented.
