Structural, magnetic, and electrical properties of Bi1-xLaxMnO3 (x=0.0, 0.1, and 0.2) solid solutions
Abstract
Possible ferromagnetic and ferroelectric orders in ceramic Bi<sub>1–<i>x</i></sub>La<sub><i>x</i></sub>MnO<sub>3</sub> (<i>x</i>= 0.0, 0.1, and 0.2) samples prepared under 3–6 GPa pressure have beeninvestigated. Rietveld fits to powder neutron diffraction data show thatBiMnO<sub>3</sub> and Bi<sub>0.9</sub>La<sub>0.1</sub>MnO<sub>3</sub> adopt a monoclinic <i>C</i>2/<i>c</i> perovskite superstructure whereas Bi<sub>0.8</sub>La<sub>0.2</sub>MnO<sub>3</sub> has orthorhombic <i>Pnma</i> symmetry. Both structural analysis and Curie–Weiss fits to magnetic susceptibility data show that high spin <i>d</i><sup>4</sup> Mn<sup>3+</sup> is present with no significant Bi deficiency or Mn<sup>4+</sup> content apparent. La substitution suppresses the magnetic Curie temperature of the monoclinic phase from 105 K for <i>x</i> = 0 to 94 K at <i>x</i> = 0.1, but the <i>x</i> = 0.2 material shows antiferromagnetic order similar to that of LaMnO<sub>3</sub>. Impedance spectroscopy and dielectric measurements on the <i>x</i>= 0.1 and 0.2 materials show modest bulk permittivity values (45–80)down to 50 K, and there is no strong evidence for ferroelectricbehavior. The two samples have thermally activated conductivities withactivation energies of 0.21–0.24 eV.
