EPR studies of VO2+ doped bis(saccharinato)bis(pyridine) zinc (II) single crystals
2009
The electron paramagnetic resonance spectra of Cu2+ impurities in bis(saccharinato)bis(pyridine)zinc(II) single crystals have been studied at room temperature in three mutually perpendicular planes. The angular variation of the spectra indicates the substitution of the host Zn2+ with Cu2+. Two magnetically inequivalent sites for Cu2+ have been observed. The spectra were fitted to the rhombic spin Hamiltonian. The spin Hamiltonian parameters and the molecular orbital coefficients were evaluated for the two sites. The ground-state wave function of Cu2+ ion in the lattice has been constructed.
