From first- to second-order phase transitions in hybrid improper ferroelectrics through entropy stabilisation
Fernando Pomiro, Chris Ablitt, Nicholas C. Bristowe +4
Hybrid improper ferroelectrics (HIFs) have been intensely studied over the last few years to gain understanding of their temperature induced phase transitions and ferroelectric swi…

A Corkscrew Model for Highly Coupled Anisotropic Compliance in Ruddlesden-Popper Oxides with Frozen Octahedral Rotations
Chris Ablitt, Mark S. Senn, Nicholas C. Bristowe +1
A "corkscrew" mechanism, that couples changes in the in-plane rotation angle to strains along the layering axis, has been proposed previously to explain increased compliance in cer…
