Comment on Dynamics distortions and polaronic effects in the paramagnetic state of La${}_{0.8}$Ba${}_{0.2}$Mn${}_{1-x}$Al${}_x$O${}_3$

Abstract

Recently, the authors of ref.[1], reported dynamics distortion and polaronic effects in the paramagnetic state of $L{a}_{0.8}B{a}_{0.2}M{n}_{1-x}A{l}_x{O}_3$ manganites. In this comment we want to complete the phase diagram(Fig3[1]) and point out of occurring spin-glass state in this manganite which is not intended for x=0.15 doping.
