Synthesis, structure and magnetic properties of (Eu1−xMnx)MnO3−δ

The solid solution (Eu1−xMnx)MnO3−δ (0 ≤ x ≤ 0.126) has been synthesized using a conventional solid-state method. Powder X-ray diffraction and selected area electron diffraction data reveal that all samples crystallize in the space group Pnma. Magnetic measurements indicate that the temperature of the paramagnetic to antiferromagnetic phase transition increases with an increase of Mn in the Eu sites. The neutron diffraction data for 153EuMnO3 at 3 K confirmed that the magnetic structure of EuMnO3 at low temperature is a canted A-type antiferromagnetic structure with the magnetic space group Pnma1′.
