Colossal Magnetoresistance is a Griffiths Singularity
M. B. Salamon, P. Lin, S. H. Chun
It is now widely accepted that the magnetic transition in doped manganites that show large magnetoresistance is a type of percolation effect. This paper demonstrates that the trans…
^{139}La Spectrum and Spin-Lattice Relaxation Measurements of La_{2/3}Ca_{1/3}MnO_3 in the Paramagnetic State
K. E. Sakaie, C. P. Slichter, P. Lin +2
^{139}La NMR measurements of La_{2/3}Ca_{1/3}MnO_3 performed in the paramagnetic state and high magnetic fields are reported. Analysis of the high temperature spectrum measured est…
Coexistence of localized and itinerant carriers near Tc in calcium-doped manganites
M. Jaime, P. Lin, S. H. Chun +3
We explore the possibility that polaronic distortions in the paramagnetic phase of LaCaMnO manganites persist in the ferromagnetic phase by considering the ob…
Low-temperature electrical transport and double exchange in La(Pb,Ca)MnO
M. Jaime, P. Lin, M. B Salamon +1
The resistivity in the ferromagnetic state of flux-grown La_{2/3}(Pb,Ca)_{1/3}MnO_3 single crystals, measured in magnetic fields up to 7 T, reveals a strong quadratic temperature d…
