Tin Titanate: the hunt for a new ferroelectric perovskite
J. Gardner, Atul Thakre, Ashok Kumar +1
We review all the published literature and show that there is no experimental evidence for homogeneous tin titanate SnTiO3 in bulk or thin-film form. Instead a combination of unrel…
Studies of Barkhausen Pulses in Ferroelectrics
C. D. Tan, J. Gardner, F. D. Morrison +2
Systems that produce crackling noises such as Barkhausen pulses are statistically similar and can be compared with one another. In this project, the Barkhausen noise of three ferro…
Quantum Critical Points in Ferroelectric Relaxors: Stuffed Tungsten Bronze K3Li2Ta5O15 and Lead Pyrochlore (Pb2Nb2O7)
Rebecca M. Smith, Jonathan Gardner, Finlay D. Morrison +7
We have synthesised ceramic specimens of the tetragonal tungsten bronze K3Li2Ta5O15 (KLT) and characterized its phase transition via X-ray, dielectric permittivity, ultrasonic spec…
PbTi1-xPdxO3: A New Room-temperature Magnetoelectric Multiferroic Device Material
Elzbieta Gradauskaite, Jonathan Gardner, Rebecca M. Smith +4
There have been a large number of papers on bismuth ferrite (BiFeO3) over the past few years, trying to exploit its room-temperature magnetoelectric multiferroic properties. Althou…
Lattice dynamics of the high temperature shape memory alloy Nb-Ru
S. M. Shapiro, G. Xu, G. Gu +2
Nb-Ru is a high temperature shape memory alloy that undergoes a Martensitic transformation from a parent cubic b-phase into a tetragonal b' phase at TM 900 C. Measurements of the p…
