RFDS studies of trigonal Er³⁺ centres in BaF₂ single crystals

Abstract

BYThe ligand hyperfine interaction (HFI) of the trigonal fluorine centre of Er3+ in B a F 2 single crystals has been investigated by the method of radiofrequency discrete saturation (RFDS) /1/9 which is the pulsed analogue of the ENDOR meth- od.The experiments have been carried out using an X-band superheterodyne F o r the c a s e of ligand nuclei with low symmetry of the ligand HFI tensor and nuclear g-tensor the spin-Hamiltonian is = > -:n=x, y, z n, m=x, y, z n, m=x, y, z are the components of the ligand HFI tensor, g?;Anm components of the nuclear g-tensor, Ag(") are pseudonuclear corrections, nm @(n) is the nuclear magneton.
