Description

We study the two-site system of three t2g orbitals and examine the possibility to effectively enhance the spin-orbit interaction (SOI) by electron correlation. The ground state of this two-site system is calculated by exactly diagonalizing the Hamiltonian, and the effective on-site and inter-atomic SOI's are calculated. Changing the number of electrons in the system, we found the conditions for the enhancement of the effective SOI's. The conditions are the intermediate Hund's coupling and the filling of four or five electrons
