Abstract
Electronic and magnetic properties are systematically investigated for doped manganites R1-xSrxMnO3 (R = La1-zNdz) by changing the nominal hole concentration x and the averaged ionic radius of the perovskite A site (z), or the one-electron bandwidth W. In the heavily doped region (x≥0.50), we observed a layered-type (A-type) antiferromagnetic state with metallic conductivity (p≈4 × 10-4 Ω cm at 5 K for La0.46Sr0.54MnO3). This observation suggests that the antiferromagnetic metallic (AFM) state is the alternative ground state for doped manganites, besides the ferromagnetic metallic (FM) state.
