The Structure of Nanoscale Polaron Correlations in La1.2Sr1.8Mn2O7
B. J. Campbell, R. Osborn, D. N. Argyriou +7
A system of strongly-interacting electron-lattice polarons can exhibit charge and orbital order at sufficiently high polaron concentrations. In this study, the structure of short-r…
Temperature Dependence of Low-Lying Electronic Excitations of LaMnO_3
M. A. Quijada, J. R. Simpson, H. D. Drew +4
We report on the optical properties of undoped single crystal LaMnO_3, the parent compound of the colossal magneto-resistive manganites. Near-Normal incidence reflectance measureme…
Observation of Kosterlitz-Thouless spin correlations in the colossally magnetoresistive layered manganite
S. Rosenkranz, R. Osborn, L. Vasiliu-Doloc +3
The spin correlations of the bilayer manganite have been studied using neutron scattering. On cooling within the paramagnetic state, we observe purely…
Charge melting and polaron collapse in
L. Vasiliu-Doloc, S. Rosenkranz, R. Osborn +7
X-ray and neutron scattering measurements directly demonstrate the existence of polarons in the paramagnetic phase of optimally-doped colossal magnetoresistive oxides. The polarons…
Spin Dynamics of the Magnetoresistive Pyrochlore Tl_2Mn_2O_7
J. W. Lynn, L. Vasiliu-Doloc, M. A. Subramanian
Neutron scattering has been used to study the magnetic order and spin dynamics of the colossal magnetoresistive pyrochlore Tl_2Mn_2O_7. On cooling from the paramagnetic state, magn…
Neutron scattering investigation of magnetic bilayer correlations in
R. Osborn, S. Rosenkranz, D. N. Argyriou +6
Neutron scattering investigations of the paramagnetic correlations in the layered manganite LaSrMnO, which exhibits colossal magnetoresistance above the…
