Atomic-environment-dependent thickness of ferroelastic domain walls
Mingqiang Li, Xiaomei Li, Yuehui Li +3
Domain walls are of increasing interest in ferroelectrics because of their unique properties and potential applications in future nanoelectronics. However, the thickness of ferroel…
Atomic-Scale Structure Relaxation, Chemistry and Charge Distribution of Dislocation Cores in SrTiO3
Peng Gao, Ryo Ishikawa, Bin Feng +3
By using the state-of-the-art microscopy and spectroscopy in aberration-corrected scanning transmission electron microscopes, we determine the atomic arrangements, occupancy, eleme…
Picometer-scale atom position analysis in annular bright-field STEM imaging
Peng Gao, Akihito Kumamoto, Ryo Ishikawa +3
We study the effects of specimen mistilt on the picometer-scale measurement of local structure by combing experiment and simulation in annular bright-field scanning transmission el…
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…
