Polaronic correlations and phonon renormalization in La1-xSrxMnO3 (x = 0.2, 0.3)
M. Maschek, J. -P. Castellan, D. Lamago +2
According to standard theory the magnetoresistance magnitude in ferromagnetic manganites crucially depends on the electron-phonon coupling strength. We showed that in La0.7Sr0.3MnO…
Interacting chains of orbital polarons in "Colossal" magnetoresistive La1-xSrxMnO3 revealed by spin and lattice dynamics
Martine Hennion, Sylvain Petit, Alexandre Ivanov +2
The origin of the effect of colossal magneto-resistance (CMR) remains still unexplained. In this work we revisit the spin dynamics of the pseudo-cubic La1-xSrxMnO3 along the Mn-O-M…
Incommensurate spin correlations in highly oxidized cobaltates LaSrCoO
Z. W. Li, Y. Drees, C. Y. Kuo +13
We observe quasi-static incommensurate magnetic peaks in neutron scattering experiments on layered cobalt oxides La2-xSrxCoO4 with high Co oxidation states that have been reported…
Polaronic metal phases in LaSrMnO uncovered by inelastic neutron and x-ray scattering
M. Maschek, D. Lamago, J. -P. Castellan +3
Among colossal magnetoresistive manganites the prototypical ferromagnetic manganite LaSrMnO has a relatively small magnetoresistance, and has been long assume…
Hour-glass magnetic spectrum in a stripe-less insulating transition metal oxide
Y. Drees, D. Lamago, A. Piovano +1
An hour-glass shaped magnetic excitation spectrum appears to be an universal characteristic of the high-temperature superconducting cuprates. Fluctuating charge stripes or alternat…
Direct observation of dynamic charge stripes in La2-xSrxNiO4
S. Anissimova, D. Parshall, G. D. Gu +8
The insulator-to-metal transition continues to be a challenging subject, especially when electronic correlations are strong. In layered compounds, such as La2-xSrxNiO4 and La2-xBax…
