Microstructures and superconducting properties of MgB2 bulk samples processed by ultra-high pressure-assisted sintering
Nanocrystalline MgB2 bulk superconductors have been fabricated by ultra-high pressure-assisted sintering (∼ 5 GPa) over a range of temperatures (700 °C-1100 °C). Phase evolution and morphology, grain size and lattice defects were systematically investigated. The superconducting performance was measu...
