Resolving competing distortions in Ca0.4Sr0.6TiO3 using complementary electron and X-ray techniques
Robin Sjökvist, Catriona A. Crawford, Richard Beanland +1
We present a study of the perovskite Ca0.4Sr0.6TiO3 using variable temperature transmission electron microscopy (TEM) and powder X-ray diffraction (PXRD). At room temperature and b…
Near-room-temperature magnetoelectric coupling engineered through inversion-breaking tilts in a bulk perovskite polytype
Struan Simpson, Urmimala Dey, Martin R. Lees +3
Systematic strategies to design properties such as ferroelectricity or magnetoelectric coupling are well established in simple perovskite materials, but they remain scarce in more…
The magnetic structure of polar -type charge and orbital ordered Hg-quadruple manganite perovskites
Ben R. M. Tragheim, Fabio Orlandi, En-Pei Liu +2
The magnetic structure of the novel HgNaMnMnO, a quadruple manganite perovskite that exhibits a unique -type charge and orbital ordered state dist…
The Microscopic Structure of Stacking Faults in SrNaNbO
Robin Sjökvist, Yining Xie, Zabeada Aslam +4
Stacking faults and other topological defects in ferroics can have a significant influence on the electronic and mechanical properties of the material. Here, regular stacking fault…
The interplay between Jahn-Teller distortions and structural degrees of freedom on pseudocubic states in manganite perovskites
Ben R. M. Tragheim, Elodie A. Harbourne, Clemens Ritter +2
The average structure of the solid solution LaMnGaO (LMGO) has been investigated from a symmetry-motivated approach utilizing synchrotron x-ray and neutron powder d…
Signatures of Orbital Order and Disorder in Fluoro-Perovskites with Electronic Degeneracies
C. A. Crawford, C. I. Hiley, J. Gainza +3
A detailed high-resolution, variable temperature powder diffraction study of the fluoro-perovskites NaFeF and NaCoF is performed to probe their orbital ordering transitions…
