Harnessing electrostatics through temperature modulations to control ferroelectrics
Cameron A. M. Scott, Xabier Diaz de Cerio, Jorge Ãñiguez-González
Temperature modulations provide an alternative method for dynamically controlling the ferroelectric state. In this paper, we use scale-independent Landau potentials and predictive…

Improper-proper ferroelectric competition as a mechanism for multistate polarisation and ferrielectric-like behaviour
Cameron A. M Scott, Finlay D. Morrison, Nicholas. C. Bristowe
In this paper, we re-explore a simple textbook Landau model describing improper ferroelectricity and show that in the limit where both proper and improper instabilities exist and c…

Universal Polar Instability In Highly Orthorhombic Perovskites
Cameron A. M. Scott, Nicholas C. Bristowe
The design of novel multiferroic ABO perovskites is complicated by the presence of necessary magnetic cations and ubiquitous antiferrodistortive modes, both of which suppress p…
