An underdog story: Re-emergence of a polar instability at high pressure in KNbO3
Mohamad Baker Shoker, Sitaram Ramakrishnan, Boris Croes +12
Ferroelectricity in perovskites is known to be suppressed by a moderate hydrostatic pressure. The notion that a polar instability should reappear in a higher pressure regime is wel…
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…
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…
Infrared phonon spectroscopy on the Cairo pentagonal antiferromagnet Bi2Fe4O9: a study through the pressure induced structural transition
M. Verseils, A. P. Litvinchuk, J-B Brubach +7
Magnetic and crystallographic transitions in the Cairo pentagonal magnet Bi2Fe4O9 are investigated by means of infrared synchrotron-based spectroscopy as a function of temperature…
Ferroelectricity in the 1 C cm range induced by canted antiferromagnetism in (LaMn)MnO
A. Gauzzi, F. Milton, V. Pascotto Gastaldo +8
Pyroelectric current and magnetoelectric coupling measurements on polycrystalline samples of the quadruple perovskite (LaMn)MnO give evidence of ferroelectricity…
Importance of non-local electron correlations in BaNiS semimetal from quantum oscillations studies
Yannick Klein, Michele Casula, David Santos-Cottin +9
By means of Shubnikov-de-Haas and de-Haas-van-Alphen oscillations, and ab initio calculations, we have studied the Fermi surface of high-quality BaNiS single crystals, with mea…
Anomalous metallic state in quasi-two-dimensional BaNiS
David Santos-Cottin, Andrea Gauzzi, Marine Verseils +6
We report on a systematic study of the thermodynamic, electronic and charge transport properties of high-quality single crystals of BaNiS, the metallic end-member of the quasi-…
