The Fermi surface and superconducting gap of MgB 2 have been studied by angle-resolved photoemission spectroscopy. Two Fermi surfaces composed of the r band and the p band are clearly observed without contaminated by the ''surface-derived'' band. The high-resolution photoemission spectra show that s
In order to improve the extrinsic superconducting properties of MgB 2 a combination of nanocrystalline microstructure and particle doping was studied with regard to the enhancement of flux pinning. For comparison, MgO and SiO 2 particles were separately introduced into the MgB 2 matrix by the in sit
