Polar State in Freestanding Strontium Titanate Nanoparticles
Trevor A. Tyson, Tian Yu, Mark Croft +6
Monodispersed strontium titanate nanoparticles were prepared and studied in detail. It is found that ~10 nm as-prepared stoichiometric nanoparticles are in a polar structural state…
Structural Changes Related to the Magnetic Transitions in Hexagonal InMnO3
T. Yu, T. A. Tyson, P. Gao +4
Two magnetic ordering transitions are found in InMnO3, the paramagnetic to antiferromagnetic transition near ~118 K and a lower possible spin rotation transition near ~42 K. Multip…
Pressure Dependent Structural Changes and Predicted Electrical Polarization in Perovskite RMnO3
T. Wu, T. A. Tyson, H. Chen +7
High pressure x-ray diffraction (XRD) measurements on RMnO3 (R=Dy, Ho and Lu) reveals that varying structural changes occurs for different R ions. Large lattice changes (orthorhomb…
Ferroelectricity in Single Crystal InMnO3
T. Yu, P. Gao, T. Wu +2
Single crystal synthesis, structure, electric polarization and heat capacity measurements on hexagonal InMnO3 show that this small R ion in the RMnO3 series is ferroelectric (space…
Local Structure of the Superconductor K0.8Fe1.6+xSe2: Evidence of Large Structural Disorder
T. A. Tyson, T. Yu, S. J. Han +4
The local structure of superconducting single crystals of K0.8Fe1.6+xSe2 with Tc = 32.6 K was studied by x-ray absorption spectroscopy. Near-edge spectra reveal that the average va…
