We present a microscopic picture of charge, orbital, and spin ordering in manganites at 50% doping by considering Jahn–Teller interaction. For spinless fermions, in two-dimensions and at 50% doping, we show that Jahn–Teller distortion and charge-orbital ordering occur simultaneously with the system in an essentially orbitally polarized state of dx2-y2 orbitals. Upon including spin degree of freedom, for small antiferromagnetic coupling, we obtain CE-type ordering.
