Abstract

The thermal transport properties and magnetic susceptibility of MgB2 have been studied. The thermoelectric power with a positive sign shows a nearly T-linear increase up to ∼150 K but shows a saturated behavior at higher temperatures, which suggests the existence of two types of charge carrier. The magnetic susceptibility above Tc shows a Pauli paramagnetism but shows a substantial T dependence which should include the information of the band structure of MgB2. The thermal conductivity shows a suppression below Tc without a clear anomaly at Tc which is a result of the reduction of the normal charge cartier concentration below Tc.
