Electronic Structure Evolution across the Peierls Metal-Insulator Transition in a Correlated Ferromagnet

Abstract

There are only a handful of materials in nature that exhibit sequential temperature-dependent transitions from a paramagnetic metal to a ferromagnetic metal phase and then onto a ferromagnetic insulator phase. Now, scientists have used spectroscopy and theoretical calculations to reveal details about such transitions in polycrystalline K${}_{2}$Cr${}_{8}$O${}_{1}6$.
