Griffiths singularities and magnetoresistive manganites
M. B. Salamon, S. H. Chun
The large, so-called colossal, magnetoresistivity of doped manganese oxides based on LaMnO3 has attracted considerable attention, but only one unusual feature of the ferromagnetic…
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…
Charge Transport in Manganites: Hopping Conduction, the Anomalous Hall Effect and Universal Scaling
Y. Lyanda-Geller, S. H. Chun, M. B. Salamon +5
The low-temperature Hall resistivity ρ_{xy} of La_{2/3}A_{1/3}MnO_3 single crystals (where A stands for Ca, Pb and Ca, or Sr) can be separated into Ordinary and Anomalous contribut…
Reentrant spin glass behavior in a layered manganite La1.2Sr1.8Mn2O7 single crystals
S. H. Chun, Y. Lyanda-Geller, M. B. Salamon +3
We report here a detailed study of AC/DC magnetization and longitudinal/transverse transport properties of LaSrMnO single crystals below = 121 K…
Breakdown of the lattice polaron picture in La0.7Ca0.3MnO3 single crystals
S. H. Chun, M. B. Salamon, Y. Tomioka +1
When heated through the magnetic transition at Tc, La0.7Ca0.3MnO3 changes from a band metal to a polaronic insulator. The Hall constant R_H, through its activated behavior and sign…
Magnetotransport in manganites and the role of quantal phases II: Experiment
S. H. Chun, M. B. Salamon, P. D. Han +2
As in conventional ferromagnets, the Hall resistivity rho_xy of a La_{2/3}(Ca,Pb)_{1/3}MnO_3 single crystal exhibits both ordinary and anomalous contributions at low temperature. H…
