Two band gap field-dependent thermal conductivity of $Mg{B}_2$

Bai-Mei Wu, Dong-Sheng Yang, Wei-Hua Zeng +6

The thermal conductivity $\kappa (H,T)$ of the new superconductor $Mg{B}_2$ was studied as a function of the temperature and a magnetic field. No anomaly in the thermal conductivity $κ(H,T…
