Evidence for centrosymmetry breaking and multiferroic properties in the A-site ordered quadruple perovskite YMnMnO
M Verseils, F Mezzadri, D Delmonte +7
By means of single-crystal X-ray diffraction we have revealed the breaking of centrosymmetry when lowering the temperature under T = 200 K concomitantly with the setting of a c…
Singling out the effect of quenched disorder in the phase diagram of cuprates
R. De Renzi, F. Coneri, F. Mezzadri +7
We investigate the specific influence of structural disorder on the suppression of antiferromagnetic order and on the emergence of cuprate superconductivity. We single out pure dis…
Optical study of the vibrational and dielectric properties of BiMnO3
W. S. Mohamed, A. Nucara, G. Calestani +5
BiMnO3 (BMO), ferromagnetic (FM) below Tc = 100 K, was believed to be also ferroelectric (FE) due to a non-centro-symmetric C2 structure, until diffraction data indicated that its…
Thermally activated magnetization reversal in bulk BiFe0.5Mn0.5O3
Davide Delmonte, Francesco Mezzadri, Chiara Pernechele +9
We report on the synthesis and characterization of BiFe0.5Mn0.5O3, a potential type-I multiferroic compound displaying temperature induced magnetization reversal. Bulk samples were…
Internal-strain mediated coupling between polar Bi and magnetic Mn ions in the defect-free quadruple-perovskite BiMnMnO
A. Gauzzi, G. Rousse, F. Mezzadri +10
By means of neutron powder diffraction, we investigated the effect of the polar Bi ion on the magnetic ordering of the Mn ions in BiMnMnO, the counterp…
Structural anomalies at the magnetic transition in centrosymmetric BiMnO
E. Montanari, G. Calestani, L. Righi +4
The structural properties of BiMn were determined from neutron powder diffraction data as a function of temperature and magnetic field. The structure at all temperatures was f…
