Cooperative dynamics in doped manganite films: phonon anomalies in the ferromagnetic state

Ch. Hartinger, F. Mayr, A. Loidl +1

We present optical measurements of phononic excitations in La${}_{2/3}$Ca${}_{1/3}$MnO${}_3$ (LCMO) and La${}_{2/3}$Sr${}_{1/3}$MnO${}_3$ (LSMO) thin films covering the full temperature ra…
