Electronic structure of the three-dimensional colossal magnetoresistiveperovskite La1-xSrxMnO3 has been established using soft-X-ray ARPES with itsintrinsically sharp definition of three-dimensional electron momentum. Theexperimental results show much weaker polaronic coupling compared to thebilayer manganites and are consistent with the GGA+U band structure. Theexperimental Fermi surface unveils the canonical topology of alternatingthree-dimensional electron spheres and hole cubes, with their shadow contoursmanifesting the rhombohedral lattice distortion. This picture has beenconfirmed by one-step photoemission calculations including displacement of theapical oxygen atoms. The rhombohedral distortion is neutral to the Jahn-Tellereffect and thus polaronic coupling, but affects the double-exchange electronhopping and thus the colossal magnetoresistance effect.
