Models of Gd3+ Paramagnetic Centers in Tetrahedral Yttrium Clusters in Cadmium Fluoride
Abstract
Zero-field splitting parameters of Gd3+ ions localized in three types of tetrahedral clusters were estimated using the superposition approximation. The cluster structures were determined from the minimum condition of the energy of a lattice with a rare earth cluster. The monoclinic centers with b20 = -345 MHz and b20 = -600 MHz were related to [CdY2GdF26] and [Cd2YGdF26] clusters, respectively.
