3/12/2024 0 Comments J tech photonicsThey fabricated a novel bulk MgB 2 via a process called spark plasma sintering (SPS). Recently, a team of researchers embarked on a journey to do so. To widen the applications of MgB 2, however, there is a need to simplify the method of its preparation. Such adjustability is not observed in conventional layered superconductors. For instance, the critical current density values ( J c) of MgB 2 can be improved by decreasing the grain size and increasing the number of grain boundaries. The intermetallic MgB 2 also allows adjustability of its properties. There has been a resurgence in the of popularity MgB 2 due to its low cost, superior superconducting abilities, high critical current density (which means that compared to other materials, MgB 2 remains a semiconductor even when larger amounts of electric current is passed through it), and trapped magnetic fields arising from strong pinning of the vortices-which are cylindrical current loops or tubes of magnetic flux that penetrate a superconductor. Almost two decades ago scientists discovered superconductivity in a new material-magnesium diboride, or MgB 2.
