Superconductors for High-Current Applications
The interest of the group is directed to material science for applications, with a special regard to superconducting materials. The research activities include crystal growth, high-pressure synthesis and thermodynamics, as well as the study and fabrication of superconducting wires and tapes and the deposition of superconducting thick films on textured Ag.
The superconducting materials of interest are both low-Tc and high-Tc compounds, namely Nb3Sn, Nb3Al, MgB2, (Bi,Pb)2Sr2Ca2Cu3O10-x/Ag (Bi2223/Ag) and YBa2Cu3O7-x. The study of the superconducting properties of these compounds and devices is performed in magnetic fields up to 17 Tesla. Critical temperature, critical current, transport properties as a function of temperature, field and strain, DC magnetisation and AC magnetic susceptibility are measured in our laboratories.
The main activities carried out under MaNEP are the development of both low- and high-Tc superconducting materials for high-current application: Nb3Sn, Nb3Al, MgB2 and Bi2223. For the first two compounds investigations focus on the processing technique and the increase of the superconducting critical current at high magnetic fields. For the last two compounds our studies include thermodynamics, bulk sintering, tape and wire fabrication and high pressure synthesis…
