Abstract
AbstractThe 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.
