Single crystals of electron-doped SrMnO3 with a cubic perovskite structurehave been systematically investigated as the most canonical(orbital-degenerate) double-exchange system, whose ground states have beenstill theoretically controversial. With only 1-2% electron doping by Cesubstitution for Sr, a G-type antiferromagnetic metal with a tiny spin cantingin a cubic lattice shows up as the ground state, where the Jahn-Teller polaronswith heavy mass are likely to form. Further electron doping above 4%, however,replaces this isotropic metal with an insulator with tetragonal latticedistortion, accompanied by a quasi-one-dimensional 3z^2-r^2 orbital orderingwith the C-type antiferromagnetism. The self-organization of such dilutepolarons may reflect the critical role of the cooperative Jahn-Teller effectthat is most effective in the originally cubic system.
