Eu0.65Sr0.35Fe_x_Mn1−_x_O3 (_x_=0.1, 0.3 and 0.5) has been prepared using a standard solid state reaction method. The under-investigation compounds is found to crystallize in a single-phase orthorhombic structure in the _P__bnm_ space group (62). The adiabatic polaron electronic transfer was obtained for all samples and the activation energy of _x_=0.1 sample is equal to 1.013 meV and slightly increase at _x_=0.3 ... Read more
