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…
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…
Magnetic Inhomogeneity and Magnetotransport in Electron-Doped Ca(1-x)La(x)MnO(3) (0<=x<=0.10)
C. Chiorescu, J. J. Neumeier, J. L. Cohn
The dc magnetization (M) and electrical resistivity (ρ) as functions of magnetic field and temperature are reported for a series of lightly electron dopedCa(1-x)La(x)MnO(3) (0<=x<=…
Polaron Transport in the Paramagnetic Phase of Electron-Doped Manganites
J. L. Cohn, C. Chiorescu, J. J. Neumeier
The electrical resistivity, Hall coefficient, and thermopower as functions of temperature are reported for lightly electron-doped Ca(1-x)La(x)MnO(3)(0 <= x <= 0.10). Unlike the cas…
