Electronic Phase Transitions in Heavy-Fermion CeB6 Compound
摘要
For the first time, an electronic phase transition at Tc ≈ 340 K in a classical strongly correlated electron system CeB6 is discovered and studied in detail. It is shown that the observed anomalies in the resistivity, thermal conductivity, specific heat, magnetization, and lattice parameters apparently correspond to the formation of a substructural charge density wave (s-CDW) at Tc, as well as to a change in configurations of dynamic charge stripes in this metal with electronic instability.
