英文摘要The spin Hamiltonian parameters and local structure for the tetragonal Rh2+ center in rhombohedral BaTiO3 are theoretically studied from the perturbation formulas of these parameters for a 4d(7) ion with low spin (S = 1/2) in tetragonally elongated octahedra. This center is ascribed to substitutional Rh2+ at the Ti4+ site in BaTiO3. The [RhO6](10-) cluster suffers relative elongation (characterized by the elongation parameter rho approximate to 0.9%) along the [100] axis due to the Jahn-Teller effect. The tetragonal elongation can entirely depress the slight trigonal distortion of the original Ti4+ site in rhombohedral BaTiO3. The calculated spin Hamiltonian parameters based on the above Jahn-Teller elongation show good agreement with the experimental results.
