“…This result means a considerably larger J value in the present system, considering that the z is roughly 2/3 times as large as that of PrScO , though the origin of this di!erence is ambiguous. In another similar perovskite, NdScO , a considerably similar value, 32 K, was obtained (12). Close values were also found for PrTiO (49 K (12)) and Nd \V TiO (&45}76 K, x"0, 0.05, and 0.1 (14)), though the Ti> moments might play an important role in these systems.…”
