Abstract

An EPR study of the paramagnetic centers formed by γ irradiation of polycrystalline NaVO3 was made at 77 K and room temperature  was performed. According to their EPR parameters and thermal behavior, the centers were attributed to: VȮ3, VȮ32-, VO, VO+, Ȯ2- radicals. The spin-spin relaxation time was calculated from the derivative peak-to-peak line widths assuming Lorentzian lines. A mechanism of the paramagnetic species formation was proposed.

Keywords
spin-lattice and spin-spin relaxation time, fine structure, hyperfine splitting
