摘要: A different 'Hubbard energy control' mechanism of the insulator-metal transition (IMT) in Mott-Hubbard insulators is discussed. This can be initiated by lattice compression and it driven a spin crossover 3d{sup 5} ions from high-spin state to low-spin state. The suppresses effective Hubbard parameter U{sub eff} down value enabling according Mott eff}/W{approx}1. classification possible scenarios metallization other n} metal compounds also performed.
