摘要: Abstract The crystallographic and magnetic structures of the distorted perovskites La 1− x Ba Mn Me O 3 (Me = or Ti) have been determined by neutron powder diffraction. MnO 6 octahedra are rotated from their ideal positions. space group Pn′ma′ allows for ferromagnetism observed in these compounds. It is not possible to decide whether, addition long range order, local spin distortions as proposed De Gennes present.
