We studied the effect of disorder on the superconducting properties of polycrystalline MgB2 by specific-heat measurements. In the pristine state, these measurements give a bulk confirmation of the presence of two superconducting gaps with 2Δ0/kBTc = 1.3 and 3.9 with nearly equal weights. The scattering introduced by irradiation suppresses Tc and tends to average the two gaps although less than predicted by theory. We also found that by a suitable irradiation process by fast neutrons, a… Expand

Temperature and field dependence of the anisotropy of MgB2.
TLDR
The anisotropy gamma of the superconducting state of high quality single crystals of MgB2 was determined, using torque magnetometry with two different methods, finding the unusual temperature dependence and can be explained by nonlocal effects of anisotropic pairing and/or the k--> dependence of the effective mass tensor.

Enhancement of the high-magnetic-field critical current density of superconducting MgB2 by proton irradiation
TLDR
It is shown that modest levels of atomic disorder induced by proton irradiation enhance the pinning of vortices, thereby significantly increasing Jc at high field strengths, and it is anticipated that either chemical doping or mechanical processing should generate similar levels of disorder, and so achieve performance that is technologically attractive in an economically viable way.
