Abstract: | VO(2+) doped single crystal of Ba(2)Zn(HCOO)(6)(H2O)(4) (BZFA) were investigated using electron paramagnetic resonance (EPR) technique at ambient temperature. Detailed investigation of EPR spectra indicated that the VO(2+) substitutes the Zn(2+) in the structure. The sites with different orientations were observed for VO(2+) in Ba(2)Zn(HCOO)(6)(H2O)(4).single crystal, but the only intense site among these sites was evaluated to obtain spin-Hamiltonian parameters, which are the principal axis values of the g and the hyperfine tensors. The covalent bonding parameter for VO(2+) and Fermi contact term were calculated using the spin-Hamiltonian parameters. |
