ESR study of Mo3+ containing mixed yttrium-scandium-aluminium garnet single crystals
Description
ESR of Mo3+ ions in mixed single crystals of yttrium-scandium-aluminium garnets Y3Al2-xScx · Al3O12, where 0 ≤ x ≤ 2 is investigated. Several new centers of Mo3+ differing from those for Y3Al5O12 single crystals are observed due to changes of symmetry and crystal field parameters associated with isomorphous substitution of octahedrally coordinated Al3+ (a) by those of Sc3+ in the third coordination sphere. Symmetry, nearest coordination, and spin-Hamiltonian parameters are estimated concerning with all Mo3+ centers in Y3Al2-xScxAl3O12 crystals for x < 0.15. It is found that in Y3Sc2Al3O12 (x = 2) the Sc3+ ions substitute also Y3+ at dodecahedral sites. (author)
