Magnetic susceptibilities of MgyU1-yO2+x solid solutions
Description
Solid solutions MgyU1-yO2+x with fluorite structure were prepared and their magnetic susceptibilities were measured from 4.2 K to room temperature. An antiferromagnetic transition was observed for the solid solutions examined in this study. Both the Neel temperature and the effective magnetic moment of uranium decreased with increasing magnesium concentration. The change in the magnetic properties of these solid solutions with x and y values was compared with that of MyU1-yO2+x solid solutions where M = Ca2+, Y3+, La3+, or Th4+. The substitution of Mg2+ for U4+ was found to oxidize uranium ions to the +5 state but not the +6 state. The variation of the effective magnetic moment of uranium against mean uranium valency is quite similar to that for the solid solutions with M = Ca2+, Y3+, or La3+
