✦ Synopsis

It was found that the mixed lanthanide orthochromate La 0.5 Pr 0.5 CrO 3 exhibits large negative magnetization when its magnetization+temperature (M+T ) curves are measured in a FC (5eld-cooled) mode with low applied 5elds (:5000 Oe). The compound shows a canted-antiferromagnetic transition at &261 K and a small peak with a positive sign at &220 K. Below this temperature, M decreases with decreasing temperature, passes through a zero value (M ‫؍‬ 0) around 163 K (T comp ), and continues to decrease steeply until &10 K. The same qualitative behavior was observed also for La 1؊x Pr x CrO 3 with 0.24 4x 4 40.8. For La 0.5 Pr 0.5 CrO 3 , the maximum absolute value of M below T comp was &40 times as large as that above T comp .
