Structure and Magnetism in the Pr1-x Nax Mn03 Perovskites(0=x=0.2)

Original language description

Complete structural determination of the Pr1-x Nax MnO3(x=0.025,0.05,0.075 and 0.20)have been investigated by the powder neutron diffraction on the diffractometer KSN-2 in Rez near Prague.The diffraction patterns were taken at lambda=0.1362 nm over a range of 2 theta=5.5-67 in steps of 0.1 at the room temperature and 7K.in order to achieve more significant lattice parameters in the course of the charge ordering transition in the x=0.2 sample,an additional X-ray diffraction measurement has been performedin low temperatures down to 80K.The electron and neutron diffraction evidences that Pr0.8 Na0.2 MnO3 exhibits a commensurate charge and orbital ordering of the Mn.3+/Mn4+(1:1)kind below Tco=215K,followed with a transition to the antiferromagnetic arrangement of pseudo-CE type at TN=175 K,analogous to that of previously studied Pr0.65 Na0.2 MnO3.
