<p>A method of manufacturing polycrystalline bulk MgB2 with enhanced superconducting properties, by introducing structural defects forming pinning sites for quantised magnetic vortices, so as to prevent them from moving under the action of the Lorentz force. Chemical dopants like Si, Cu, Zn, Al, C, Li, or N or inert or nano-boride forming particles like Y2O3 can be used.</p> |
