Abstract

The dynamic spin Hamiltonian form for an Fe³⁺ ion in TiO₂ is given and its spin-lattice coefficients computed. On the basis of the change of resonance field with induced stress in an ESR experiment, the quadrupolar contributions SdS is found to exceed by two orders of magnitude the dipolar contribution beta HhS. A complete set of nine spin-lattice coefficients for SdS in orthorhombic symmetry is determined.
