Electron-doped manganites based on CaMnO3

The work is devoted to a review of magnetic, electrical, and optical properties of electron-doped manganites Ca1 − x Ln x MnO3 (Ln stands for rare-earth ions) at the concentrations of the doping ions x from 0 to 0.2. The main attention is paid to the data obtained using single crystals containing vacancies in both the anion and cation sublattices. The features of the multiphase state of the Ca1 − x Ln x MnO3 manganites (x < 0.2) are discussed.
