Uncorrelated and correlated nanoscale lattice distortions in the paramagnetic phase of magnetoresistive manganites

V. Kiryukhin, A. Borissov, J. S. Ahn +3

Neutron scattering measurements on a magnetoresistive manganite La${}_{0.75}$(Ca${}_{0.45}$Sr${}_{0.55}$)${}_{0.25}$MnO${}_3$ show that uncorrelated dynamic polaronic lattice distortions are…
