Electron paramagnetic resonance study of $VO^{2+}$ doped single crystal of ferroelectric guanidinium uranyl sulphate trihydrate

Abstract

We report result obtained from an EPR study of vanadyl ion ($VO^ {2+}$) in a single crystal of ferroelectric guanidinium uranyl sulphate trihydrate. The Spin-Hamiltonian parameters were also determined via EPR data. $VO^ {2+}$ enters the lattice interstitially at two distinguishable sites and resulting vanadyl complexes have nearly axial symmetry.
