“…Taking into account the proximity of the principal axis deviation of center Gd 2 in the yttrium silicate to the similar value for a single gadolinium center found in the scandium Other situation in the discussed silicates occurs for odd isotope of 143 Nd 3+ rare-earth ion (R i = 0.983 Å [16]). Both in Y 2 SiO 5 (g z = 4.1038) [17,18] and in Sc 2 SiO 5 (g z = 3.48) [19], only one 143 Nd 3+ center is observed. The modulation envelope analysis in [20] carried out by three-pulse electron spin echo procedure on samples with 28 Si isotope has found that 143 Nd 3+ center in Y 2 SiO 5 was attributable to the neodymium ion in the yttrium position with seven-fold oxygen environment.…”

The study of grown Sc2SiO5 : Gd and Sc2SiO5 : Fe crystals was carried out by the paramagnetic resonance method. It has been established that Fe3+ ions replace Sc3+ in both crystallographic positions, while Gd3+ ions exhibit a single center localized in a larger position with a coordination number of 7. Measurement of the orientational behavior of the positions of transitions of Fe3+ and Gd3+ centers in two orthogonal planes made it possible to determine the parameters of their triclinic spin Hamiltonians. To determine the localization of impurity ions Cr3+, Fe3+ and Gd3+ in scandium and yttrium silicates, the orientation of the main Z axes of the fine structure tensors of the second rank was used. Keywords: scandium and yttrium silicates, impurity ions, paramagnetic resonance.

“…Иная ситуация в обсуждаемых силикатах складывается для нечетного изотопа редкоземельного иона 143 Nd 3+ (R i = 0.983 ¦ [16]). Как в Y 2 SiO 5 (g z = 4.1038) [17,18], так и в Sc 2 SiO 5 (g z = 3.48) [19] наблюдается только по одному центру 143 Nd 3+ . В работе [20] в результате анализа огибающей модуляции в методике трехимпульсного электронного спинового эха на образцах с изотопом 28 Si было установлено, что центр 143 Nd 3+ в Y 2 SiO 5 обусловлен ионом неодима в позиции иттрия с семикратным кислородным окружением.…”

The EPR spectrum of yttrium and scandium silicate single crystals doped with chromium has been studied at various frequencies. Y_2SiO_5 has one triclinic Cr^3+ center, while the Sc_2SiO_5 crystals demonstrate two nonequivalent centers. The spin Hamiltonian parameters of these centers have been determined. These centers are found to be tricharged chromium ions localized in the yttrium and scandium positions.
