摘要： A description is given of the composition and preparation of single phase crystals having a garnet structure and a lattice constant smaller than 11.9 .ANG.. The garnets correspond to the formula{Mn.sub.3-a-b Mg.sub.a M.sub.b }[Al.sub.2-c M'.sub.c ](Ge.sub.3-d-e Si.sub.d M".sub.e)O.sub.12 (I)wherein0.0.ltoreq.a.ltoreq.0.40.0.ltoreq.b.ltoreq.0.40.0.ltoreq.c.ltoreq.0.20.0.ltoreq.d.ltoreq.0.50.0.ltoreq.e.ltoreq.0.60.2.ltoreq.a+d.ltoreq.0.8.
