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…

Observation of Anomalous Phonons in E-Type Orthorhombic REMnO3
P. Gao, H. Y. Chen, T. A. Tyson +5
We observe the appearance of a phonon near the lock-in temperature in orthorhombic REMnO3 (RE: Lu and Ho) and anomalous phonon hardening in orthorhombic LuMnO3. The anomalous phono…
