Structural evolution and ferroelectric (FE)-to-antiferroelectric (AFE) transition behaviors were observed in Bi1-δFe0.95Mn0.05O3 (100)-textured films with a carefully controlled Bi deficiency concentration δ. Raman spectra revealed an orthorhombic structural transition induced by Mn substitution. The polarization-electric field hysteresis loops and capacitance-voltage loops of Bi1-δFe0.95Mn0.05O3 films clearly demonstrated antiferroelectric behavior with increasing δ. The responses of the…

TLDR
A change of the conduction mechanism also seems to take place from a bulk-limited to an interface-limited transport as x increases, which is attributed to the ferroelectric to paraelectric phase transition which is controlled with the increase of x.

TLDR
No evidence is found for any systematic variation of the electric or magnetic properties of BiFeO(3) depending on the transition metal dopant, suggesting that these properties are determined mainly by extrinsic effects arising from defects or grain boundaries.
A Strain-Driven Morphotropic Phase Boundary in BiFeO3
TLDR
Electric field–dependent studies show that a tetragonal-like phase can be reversibly converted into a rhombohedral- like phase, accompanied by measurable displacements of the surface, making this new lead-free system of interest for probe-based data storage and actuator applications.

TLDR
Dynamically tuning the concentration and profile of ions and vacancies in transition metal oxides provides a route to control of new functionalities that have led to the widespread use of oxides and may form the basis of new device paradigms, such as the control of magnetism with electric fields.
