摘要:

We present high resolution (40 meV) angle-resolved photoemission data from cleaved single-crystalline surfaces of the layered colossal magnetoresistive oxide La1.2Sr1.8Mn2O7. The sample was in the low temperature ferromagnetic state atT=10 K, well below the phase transition temperature ofT=126 K. Full valence bands containing Mn 3dand O 2pstates are shown, as well as blowups of the nearEFspectra which are made up of theegsymmetry Mn 3d-O 2phybrid states.k-vectors span the Brillouin zone center (0,0) to the zone face (π,0).
