An x-ray diffraction study of the temperature-induced structural phase transitions in SmVO3
R. D. Johnson, C. C. Tang, I. R. Evans +7
Through powder x-ray diffraction we have investigated the structural behavior of SmVO3, in which orbital and magnetic degrees of freedom are believed to be closely coupled to the c…
Magneto-orbital helices and multiferroicity
N. J. Perks, R. D. Johnson, C. Martin +2
Orbitally ordered states evolving coincidentally with structural distortions and magnetic ordering provide a novel route to controlling electronic and magnetic properties of materi…
The Magnetic Structure of DyMn2O5 Determined by Resonant X-ray Scattering
G. E. Johnstone, R. A. Ewings, R. D. Johnson +3
Resonant magnetic x-ray scattering has been used to investigate the magnetic structure of the magnetoelectric multiferroic DyMn2O5. We have studied the magnetic structure in the fe…
Electric field control of the magnetic chiralities in ferroaxial multiferroic RbFe(MoO4)2
Alexander J. Hearmon, Federica Fabrizi, Laurent C. Chapon +5
The coupling of magnetic chiralities to the ferroelectric polarisation in multiferroic RbFe(MoO) is investigated by neutron spherical polarimetry. Because of the axiality o…
Electric field control of chiral magnetic domains in the high-temperature multiferroic CuO
P. Babkevich, A. Poole, R. D. Johnson +3
We have studied the high temperature multiferroic cupric oxide using polarized neutron diffraction as a function of temperature and applied electric field. We find that the chiral…
