Coupling of phonons with orbital dynamics and magnetism in CuSbO
D. T. Maimone, A. B. Christian, J. J. Neumeier +1
Strongly interacting phonons and orbital excitations are observed in the same energy range for CuSbO, unlocking a so-far unexplored type of electron-phonon interaction. An…
Giant electro-thermal conductivity and spin-phonon coupling in an antiferromagnetic oxide
C. Chiorescu, J. J. Neumeier, J. L. Cohn
The application of weak electric fields (<~ 100 V/cm) is found to dramatically enhance the lattice thermal conductivity of the antiferromagnetic (AF) insulator CaMnO(3) over a broa…
Hydrostatic pressure effects on the electrical transport properties of Pr0.5Sr0.5MnO3
F. J. Rueckert, M. Steiger, B. K. Davis +3
We studied single-crystalline Pr0.5Sr0.5MnO3 by means of measurements of magnetic susceptibility and specific heat at ambient pressure (P), and electrical resistivity (r) in hydros…
Relationship between macroscopic physical properties and local distortions of low doping La{1-x}Ca{x}MnO3: an EXAFS study
Y. Jiang, F. Bridges, L. Downward +1
A temperature-dependent EXAFS investigation of La{1-x}Ca{x}MnO3 is presented for the concentration range that spans the ferromagnetic-insulator (FMI) to ferromagnetic-metal (FMM) t…
Impurity Conduction and Magnetic Polarons in Antiferromagnetic Oxides
C. Chiorescu, J. L. Cohn, J. J. Neumeier
Low-temperature transport and magnetization measurements for the antiferromagnets SrMnO(3) and CaMnO(3) identify an impurity band of mobile states separated by energy E from electr…
Doping Dependence of Polaron Hopping Energies in La(1-x)Ca(x)MnO(3) (0<= x<= 0.15)
K. P. Neupane, J. L. Cohn, H. Terashita +1
Measurements of the low-frequency (f<= 100 kHz) permittivity at T<= 160 K and dc resistivity (T<= 430 K) are reported for La(1-x)Ca(x)MnO(3) (0<= x<= 0.15). Static dielectric const…
