Electron Doped CaMnO₃: Mn-Site Substitution versus Ca-Site Substitution

Abstract:

The magnetic, transport, optical, and elastic properties of the electron-doped manganites CaMn1-xMxO3 with Mn-site doping (M=Mo or W, x≤0.20) are studied and the results are compared with those of Ca-site substituted manganites with the same Mn3+ concentration. If Mn3+ concentration is lees than 10%, the charge carriers' localization due to lattice distortions in the Ca-site doped samples is stronger than the localization caused by magnetic dilution in the case of Mn-site substitution. At higher Mn3+ concentration, the magnetic dilution plays a key role.
