Specific heat of MgB2 after irradiation

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 2*D0/kBTc = 1.3 and 3.9 with nearly equal weights. The scatte...
