Strain engineering a multiferroic monodomain in thin-film BiFeO
N. Waterfield Price, A. M. Vibhakar, R. D. Johnson +6
The presence of domains in ferroic materials can negatively affect their macroscopic properties and hence their usefulness in device applications. From an experimental perspective,…
Observation of magnetic vortex pairs at room temperature in a planar α-Fe2O3/Co heterostructure
F. P. Chmiel, N. Waterfield Price, R. D. Johnson +8
Vortices are among the simplest topological structures, and occur whenever a flow field `whirls' around a one-dimensional core. They are ubiquitous to many branches of physics, fro…
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…
Coherent magneto-elastic domains in multiferroic BiFeO3 films
N. Waterfield Price, R. D. Johnson, W. Saenrang +6
The physical properties of epitaxial films can fundamentally differ from those of bulk single crystals even above the critical thickness. By a combination of non-resonant x-ray mag…
