Abstract:

A hyperfine structure of EPR signals of odd isotopes Gd3+ in Pb5Ge3O11, PbMoO4, and YVO4 single crystals has been investigated at different temperatures. The observation of forbidden (with the nuclear spin flip) transitions has made it possible to determine quadrupole interaction P (2) (0) associated with the gradient of the electric field of ligands at the impurity. It has been shown for the first time that, under the condition |P (2) (0) | a parts per thousand yen |A (x, y) | (A (i) are the tensor components), not only the magnitudes of splitting but also the observed asymmetry in a hyperfine structure (in perpendicular orientations of the magnetic field) depends on mutual signs of parameters of initial splitting b (2) (0) and P (2) (0) . Results of studying the spectra have demonstrated that |b (2) (0) (T)|/|P (2) (0) (T)| similar to const for a concrete single crystal, which assumes the similarity of physical mechanisms determining these parameters.
