The DC magnetic susceptibility $\chi$ was measured for sintered YBa2Cu3Oy from 77 K to $800\sim 900$ K in heating “up” and cooling “down” processes. After subtracting the contribution of isolated Cu spins, the $\chi$ of the “down” process, in which $y{\sim}6$, showed a rapid decrease as temperature decreased at about 300 K ($T_{0}$), and this $\chi$ behavior proved the existence of long-range antiferromagnetic ordering below $T_{0}$ in $y{\sim}6$ system.
