Signatures of electronic polarons in La${}_{1-x}$Sr${}_{1+x}$MnO${}_4$ observed by electron energy-loss spectroscopy

R. Kraus, M. Schrade, R. Schuster +4

The dielectric properties of La${}_{1-x}$Sr${}_{1+x}$MnO${}_4$ single crystals with x = 0, 0.125, 0.25, and 0.5 were studied by means of electron energy-loss spectroscopy as a function o…
