摘要：

Neutron diffraction measurements on the title compounds have been carried out over a range of temperature from 10 to 300 K. The compounds have a rhombohedrally distorted perovskite structure. A paramagnetic to ferromagnetic transition is observed for samples with x greater than or equal to 0.2. The ordered magnetic moments obtained for x = 0.2 and 0.3 are found to be 1.5 and 1.89 mu(B) respectively at 10 K and are in agreement with those reported from other macroscopic measurements. A possible magnetic structure is discussed.
