Abstract:
For the first time, an electronic phase transition at $T_c \approx 340$ K in a classical strongly correlated electron system CeB$_6$ 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 $T_c$, as well as to a change in configurations of dynamic charge stripes in this metal with electronic instability.

The work of N.B. Bolotina and V.M. Gridchina on the structural analysis was supported by the Ministry of the Science and Higher Education of the Russian Federation (state assignment for the National Research Center Kurchatov Institute). The preliminary measurements of CeB$_6$ crystals were supported by the European Microkelvin Platform (EMP).
