Complex magnetic phases and thermodynamics of CuB_2O_4
C. H. Lai, M. -J. Hsieh, N. Puri +9
The copper metaborate CuB_2O_4(CBO) has been studied within the parametric space of magnetic field (B) and temperature (T), showing a series of distinct phases, including commensur…
Octahedral Tilt Instability of ReO_3-type Crystals
Philip B. Allen, Yiing-Rei Chen, Santanu Chaudhuri +1
The octahedron tilt transitions of ABX_3 perovskite-structure materials lead to an anti-polar (or antiferroelectric) arrangement of dipoles, with the low temperature structure havi…
Polaronic Signatures in Mid-Infrared Spectra: Prediction for LaMnO3 and CaMnO3
Yiing-Rei Chen, Vasili Perebeinos, Philip B. Allen
Hole-doped LaMnO3 and electron-doped CaMnO3 form self-trapped electronic states. The spectra of these states have been calculated using a two orbital (Mn eg Jahn-Teller) model, fro…
Spin versus Lattice Polaron: Prediction for Electron-Doped CaMnO3
Yiing-Rei Chen, Philip B. Allen
CaMnO3 is a simple bi-partite antiferromagnet(AF) which can be continuously electron-doped up to LaMnO3. Electrons enter the doubly degenerate E_g subshell with spins aligned to th…
