| 摘要 | The electron paramagnetic resonance (EPR) parameters (the anisotropic g factors g(x), g(y), g(z), and the hyperfine structure constants A(x), A(y), and A(z)) of the two orthorhombic Er3+ centers in Bi2Sr2YCu2O8 are theoretically studied from the perturbation formulas of these parameters for a 4f(11) ion in orthorhombic symmetry. In these formulas, the contributions due to the admixtures of various states are taken into account, and the orthorhombic field parameters are determined from the superposition model and the local geometry of Bi3+ site in Bi2Sr2YCu2O8. The calculated EPR parameters show reasonable agreement with the observed values. The anisotropy g(z) > g(x)(g(y)) for the g factors may be attributed to the compression of the ligand octahedra in the Er3+ centers. |
