Dynamical magnetism in the disordered cubic lattice material $I^^{3}$ - $Ba_{3} CoNb_{2} O_{9}$

Fanjun Xu, Ralf Feyerherm, Cecilie Glittum +12

$I^^{3}$ - $Ba_{3} CoNb_{2} O_{9}$ realizes a disordered simple-cubic spin- $1/2$ lattice in which Co $^{2 +}$ ions randomly occupy one third of the sites, placing the syste…

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 LaMn $_{1 - x}$ Ga $_{x}$ O $_{3}$ (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 $t_{2 g}$ 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 $_{3}$ and NaCoF $_{3}$ is performed to probe their orbital ordering transitions…

Goldstone-mediated polar instability in hexagonal barium titanate

S. Simpson, U. Dey, R. J. SjÃ¶kvist +5

We discover a rare structural manifestation of the Goldstone paradigm in a hexagonal polytype of the archetypal ferroelectric BaTiO3. First-principles calculations confirm the Gold…
