Polaron Glass in La$_{0.35}$Pr$_{0.275}$Ca$_{0.375}$MnO$_3$*

Manganite compounds in the La$_{1-x-y}$Pr$_y$Ca$_x$MnO$_3$ series are known for exhibiting phase separation over a large temperature range. We combined the x-ray photoemission electron microscopy (PEEM) and resonant elastic soft x-ray scattering (REXS) techniques to study the interplay between the ferromagnetic and charge-ordered/antiferromagnetic phases, respectively, in La$_{0.35}$Pr$_{0.275}$Ca$_{0.375}$MnO$_3$. We found a polaronic glassy state at intermediate temperatures, when the material is dominated by charge- and orbital-order domains. When the sample is cooled below T$_{\mathrm{C}}$, the magnetization increases, accompanied by a relaxation of the lattice deformations that accompany the polaron glass.
