Universal magneto-orbital ordering in the divalent $A$ -site quadruple perovskite manganites $A$ Mn $_{7}$ O $_{12}$ ( $A$ = Ca, Sr, Cd, and Pb)

R. D. Johnson, D. D. Khalyavin, P. Manuel +4

Through analysis of variable temperature neutron powder diffraction data, we present solutions for the magnetic structures of SrMn $_{7}$ O $_{12}$ , CdMn $_{7}$ O $_{12}$ , and PbMn $_{7}$ O$_{12…

Temperature induced phase transition from cycloidal to collinear antiferromagnetism in multiferroic Bi $_{0.9}$ Sm $_{0.1}$ FeO $_{3}$ driven by $f$ - $d$ induced magnetic anisotropy

R. D. Johnson, P. A. McClarty, D. D. Khalyavin +3

In multiferroic BiFeO $_{3}$ a cycloidal antiferromagnetic structure is coupled to a large electric polarization at room temperature, giving rise to magnetoelectric functionality that…
