Strain and Magnetic Field Induced Spin-Structure Transitions in Multiferroic BiFeO3
A. Agbelele, D. Sando, C. Toulouse +17
The magnetic-field-dependent spin ordering of strained BiFeO3 films is determined using nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy t…
Electrical switching of magnetic polarity in a multiferroic BiFeO3 device at room temperature
N. Waterfield Price, R. D. Johnson, W. Saenrang +4
We have directly imaged reversible electrical switching of the cycloidal rotation direction (magnetic polarity) in a (111)-BiFeO3 epitaxial-film device at room temperature by non-r…
Non-ferroelectric nature of the conductance hysteresis in CH3NH3PbI3 perovskite-based photovoltaic devices
J. Beilsten-Edmands, G. E. Eperon, R. D. Johnson +2
We present measurements of conductance hysteresis on CH3NH3PbI3 perovskite thin films, performed using the double-wave method, in order to investigate the possibility of a ferroele…
Magnetically-induced ferroelectricity in the (ND4)2[FeCl5(D2O)] molecular compound
Jose Alberto Rodriguez-Velamazan, Oscar Fabelo, Angel Millan +3
The number of magnetoelectric multiferroic materials reported to date is scarce, as magnetic structures that break inversion symmetry and induce an improper ferroelectric polarizat…
First-principles study of structurally modulated multiferroic CaMnO
Kun Cao, Roger D. Johnson, Natasha Perks +2
We study the electronic and magnetic structures of multiferroic CaMnO by first-principle calculations, based on the experimentally determined modulated crystal structure…
