Observation of charge-density-wave excitations in manganites
A. Nucara, P. Maselli, P. Calvani +6
In the optical conductivity of four different manganites with commensurate charge order (CO), strong peaks appear in the meV range below the ordering temperature T_{CO}. They are s…
Effect of Mn substitution by Ga on the optical properties of a metallic manganite
A. Nucara, P. Maselli, M. Del Bufalo +5
In a metallic manganite like La(2/3)Sr(1/3)MnO(3), the substitution of Mn(+3) by Ga(+3) dilutes the ferromagnetic order and locally cancels the Jahn-Teller distortion, without heav…
Evidence of ultra-slow polaron dynamics in low-doped manganites from 139La NMR-NQR and muon spin rotation
G. Allodi, M. Cestelli Guidi, R. De Renzi +2
We report a 139La NMR investigation of low-doped insulating manganite samples (LaMnO(3+y) and La(1-x)Ca(x)MnO(3+y)) as a function of temperature. A volume fraction with fast nuclea…
Staggered magnetization, critical behavior and weak ferromagnetic propert ies of LaMnO by muon spin rotation
M. Cestelli Guidi, G. Allodi, R. De Renzi +4
We present a study of a microtwinned single crystal of LaMnO by means of implanted muons. Two muon stopping sites are identified from the symmetry of the internal field in the…
