Temperature induced in-gap states in the band structure and the insulator-metal transition in LaCoO3

S. Ovchinnikov, Yu. Orlov, I. Nekrasov +1

For many years a spin-state transition at $T\approx 100K$ and insulator - metal transition (IMT) at $T_{IMT}\approx 600K$ in LaCoO${}_3$ remains a mystery. Small low-spin - high…
