Fig. 1 (Color online) A schematic view of the magnetic mixed spin system in a cubic lattice, consisting of two sublattices $A$ and $B$ with spin $S_A$=1 and $S_B$=1/2. The exchange interactions for $z$ spin direction and ($x, y$) plane are respectively $J_z$ (green dashed line) and $J_{xy}$ (brown dashed line). The dilution is restricted to $S_A$ sites.
