Permanent magnet with MgB2 bulk superconductor
Superconductors with persistent zero-resistance currents serve as permanent magnets for high-field applications requiring a strong and stable magnetic field, such as magnetic resonance imaging (MRI). The recent global helium shortage has quickened research into high-temperature superconductors (HTSs)—materials that can be used without conventional liquid-helium cooling to 4.2 K. Herein, we demo...
متن کاملPreparation and Characterization of MgB2 Superconductor
Superconducting MgB2 crystallites having a size up to 3 X 2 X 1 mm have been grown using a liquidassisted-sintering process under atmospheric pressure of argon. The magnetization measurements have been carried out on MgB2 samples to determine upper critical field, critical current density and irreversibility line. The obtained values of critical current density and upper critical field were ~10...

متن کاملSuperconducting Microwave Cavity Made of Bulk MgB2
We report the successful manufacture and characterization of a microwave resonant cylindrical cavity made of bulk MgB2 superconductor (Tc ≈ 38.5 K), which has been produced by the Reactive Liquid Mg Infiltration technique. The quality factor of the cavity for the TE011 mode, resonating at 9.79 GHz, has been measured as a function of the temperature. At T = 4.2 K, the unloaded quality factor is ...
متن کاملModelling of bulk superconductor magnetization
This paper presents a topical review of the current state of the art in modelling the magnetization of bulk superconductors, including both (RE)BCO (where RE = rare earth or Y) and MgB2 materials. Such modelling is a powerful tool to understand the physical mechanisms of their magnetization, to assist in interpretation of experimental results, and to predict the performance of practical bulk su...
