Nature of Disorder in Relaxor-like Ferroelectric AB(HCO2)3 Frameworks

Abstract: Relaxor ferroelectics are of significant interest for use as piezoelectric actuators in sensing applications and for high precision mechanical stages. Relaxors are traditionally associated with disorder induced by a complex mixture of cations in complex oxides. Recently framework materials built from inorganic and organic building blocks have been shown to exhibit relaxor-like properties without the requirement for such complex doping, a unique avenue to such behaviour. We propose to study two of these relaxor-like ferroelectrics, NH4Mn(HCO2)3 and NH4Zn(HCO2)3, using quasielastic neutron scattering to establish the dynamics of the disorder responsible for their physical properties and how this varies with the different relaxor properties of these materials and between their polar and non-polar phases. This will be complimented by NMR and diffraction measurements currently underway.
