Abstract
A garnet-structure complex oxide powder having formula (1) is prepared by adding an aqueous solution containing (a) Tb ion, an aqueous solution containing (b) Al ion, and an aqueous solution containing (c) Sc ion to a co-precipitating aqueous solution, to induce a co-precipitate of components (a), (b) and (c), filtering, heat drying and firing the co-precipitate.(RSc)(ASc)O  (1)R is yttrium or a lanthanoid element, typically Tb, A is a Group 13 element, typically Al, x and y are 0<x<0.08 and 0.004<y<0.16.
