Abstract (en)
[origin: WO2011101584A1] The aim of the invention is to provide a crystalline compound of formula Lnx. (1-t1-t2-t3-t4) Ybx.t1Erx. t2Tmx. t3Hox. t4BayZnzO1. 5x+y+z where: Ln is Y, Gd or La, t1+t2+t3+t4 varies from 0.001 to 0.3, preferably from 0.01 to 0.2, and such that when x=2, y=1, z=1, t1+t3+t4 is nonzero if Ln is La or Gd and if t3+t4 is zero, then t1 varies from 0.05 to 0.1 and t2 varies from 0.02 to 0.07 if Ln is Gd, then t2+t4 is nonzero.
