This mechanism can be initiated by the lattice compression and it is driven by a spin crossover of 3d(5) ions from the high-spin state to the low-spin state. The spin crossover suppresses the effective Hubbard parameter U-eff down to the value enabling the insulator-metal transition according to the Mott mechanism U-eff/W approximate to 1. The classification of possible scenarios of metallization in the other 3d(n) metal compounds is also performed.
