Abstract

Single-crystal electron microprobe analysis of a lanthanum lutetium gallium garnet has resulted in a composition of La_2.37Nd _0.07Pb_0.01Lu_2.54Cr_0.01 Ga _3.00O₁₂. This composition gives better agreement between observed and calculated total dielectric polarizabilities than previously reported compositions (La_2.26-2.32Nd_0.04Lu _2.57-2.63Ga_3.07O₁₂ by x-ray fluorescence and La_2.655Nd_0.027Lu_2.656Ga_2.655O ₁₂ by inductively coupled plasma analyses), and does not imply the crystal-chemically improbable presence of Lu³⁺ in the tetrahedral site. X-ray and neutron crystal-structure analyses have confirmed that little or no Lu resides in this site.
