Paramagnetic resonance of Gd³⁺ ions in nonstoichiometric fluorite R_xM_1‑xF_2+x (R = Y, Gd; M = Ca, Cd)

EPR studies of Y_0.03Ca_0.97F_2.03: Gd³⁺ and Y_0.03Cd_0.97F_2.03: Gd³⁺ single crystals revealed the presence of Gd³⁺ ions embedded in yttrium clusters. The symmetry of the paramagnetic centers was determined, and the fine-structure parameters were estimated both experimentally and theoretically.
