A complete diagonalization (of energy matrix) method (CDM) for 4f 1 ions in tetragonal symmetry under an external magnetic field is applied to calculate the spin-Hamiltonian parameters (g factors g J , g ? and hyperfine structure constants A J , A ? ) for Pr 4+ ion at the tetragonally distorted dode
Based on the defect models that the two tetragonal Cu 2+ centers in KTaO 3 are due to Cu 2+ ions at Ta 5+ sites associated, respectively, with one and two oxygen vacancies (V 0 ) along C 4 axis because of charge compensation, the spin-Hamiltonian parameters (g factors g // , g β₯ and hyperfine struct
