Direct observation of Jahn-Teller critical dynamics at a charge-order Verwey transition
Vinícius Pascotto Gastaldo, Mala N. Rao, Alexey Bosak +10
By means of diffuse and inelastic x-ray scattering (DS,IXS), we probe directly the charge-ordering (CO) dynamics in the Verwey system (NaMn)MnO, where a peculiar qua…
Evolution of magneto-orbital order upon B-site electron doping in Na1-xCaxMn7O12 quadruple perovskite manganites
R. D. Johnson, F. Mezzadri, P. Manuel +3
We present the discovery and refinement by neutron powder diffraction of a new magnetic phase in the Na1-xCaxMn7O12 quadruple perovskite phase diagram, which is the incommensurate…
Commensurate structural modulation in the charge- and orbitally-ordered phase of the quadruple perovskite (NaMn)MnO
A. Prodi, A. Daoud-Aladine, F. Gozzo +9
By means of synchrotron x-ray and electron diffraction, we studied the structural changes at the charge order transition =176 K in the mixed-valence quadruple perovskite (N…
Synthesis and characterization of multiferroic BiMnO
F. Mezzadri, G. Calestani, M. Calicchio +5
We report on the high pressure synthesis of BiMnO, a manganite displaying a "quadruple perovskite" structure. Structural characterization of single crystal samples shows…
