Pressure-temperature phase diagram of charge ordering in Nd1/2Sr1/2MnO3
P. Maselli, D. Nicoletti, A. Nucara +5
We observe how the charge-ordering (CO) temperature of Nd1/2Sr1/2MnO3 decreases with the external pressure p from 160 K at p = 0 down to 30 K at p ~ 4.5 GPa, by measuring the value…
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…
Reflectivity measurements in uniaxial superconductors: a methodological discussion applied to the case of La(2-x)Sr(x)CuO(4)
M. Ortolani, P. Calvani, S. Lupi +3
Most of the novel superconductors are uniaxial crystals, with metallic planes () orthogonal to an insulating axis (). Far-infrared measurements of the reflectivity $R_{ab} (…
Lucarelli et al. reply to Tajima et al. (cond-mat 0303493)
A. Lucarelli, S. Lupi, M. Ortolani +3
In their Comment to a recent paper of ours [Lucarelli et al., PRL 92, 037002 (2003)], Tajima et al. (cond-mat 0303493) argue that the samples of La(2-x)Sr(x)CuO(4) where we find fa…
Infrared signatures of charge stripes in La(2-x)Sr(x)CuO(4)
A. Lucarelli, S. Lupi, M. Ortolani +9
The in-plane optical conductivity of seven La(2-x)Sr(x)CuO(4) single crystals with x between 0 and 0.15 has been studied from 30 to 295 K. All doped samples exhibit strong peaks in…
Optical conductivity of the nonsuperconducting cuprate La(8-x)Sr(x)Cu(8)O(20)
A. Lucarelli, S. Lupi, P. Calvani +7
La(8-x)Sr(x)Cu(8)O(20) is a non-superconducting cuprate, which exhibits a doubling of the elementary cell along the c axis. Its optical conductivity sigma (omega) has been first me…
