Observation of cation-specific critical behavior at the improper ferroelectric phase transition in Gd2(MoO4)3
Inger-Emma Nylund, Maria Tsoutsouva, Tor Grande +1
Gadolinium molybdate is a classical example of an improper ferroelectric and ferroelastic material. It is established that the spontaneous polarization arises as a secondary effect…
Goldstone-like phonon modes in a (111)-strained perovskite
A. Marthinsen, S. M. Griffin, M. Moreau +3
Goldstone modes are massless particles resulting from spontaneous symmetry breaking. Although such modes are found in elementary particle physics as well as in condensed matter sys…
Strain controlled oxygen vacancy formation and ordering in CaMnO
Ulrich Aschauer, Reto Pfenninger, Sverre M. Selbach +2
We use first-principles calculations to investigate the stability of bi-axially strained \textit{Pnma} perovskite CaMnO towards the formation of oxygen vacancies. Our motivatio…
Phase diagram of silica from computer simulation
Ivan Saika-Voivod, Francesco Sciortino, Tor Grande +1
We evaluate the phase diagram of the ``BKS'' potential [Van Beest, Kramer and van Santen, Phys. Rev. Lett. 64, 1955 (1990)], a model of silica widely used in molecular dynamics (MD…
