Microstructural Features of Magnetic NiCoB Nanoparticles Addition to MgB2 Precursor Powders

[摘要] Magnesium diboride (MgB2) is a superconductor characterized by interesting properties like rather high superconducting transition temperature Tc = 39 K, long coherence length and low anisotropy. In addition, it has a very simple crystal structure and low density. Those properties make the MgB2 an ideal candidate for a wide range of applications.
