Band filling effect on polaron localization in La${}_{1-x}($Ca${}_y$Sr${}_{1-y}$)${}_x$MnO${}_3$ manganites

G. Allodi, R. De Renzi, K. Zheng +6

We report on an a $\mu$SR and ${}^{55}$Mn NMR investigation of the magnetic order parameter as a function of temperature in the optimally doped La${}_{5/8}$(Ca${}_y$Sr${}_{1-y}$)${}_{3/8}$MnO$…
