Query: Magnetization Distribution in the layered CMR Manganite La1.2Sr1.8Mn2O7
  from Polarized Neutron Diffraction   In the ferromagnetic metallic state of the colossal magnetoresistive (CMR)
manganite La1.2Sr1.8Mn2O7, the spin density distribution is essentially in
agreement with the standard picture in which the unpaired electrons occupy the
three t2g orbitals, dxy, dyz, and dxz. However we find a small spin density ~4%
of the total Mn spin) on the apical O(2) oxygen atom at both 100 K and 220 K
and we suggest that this is due to covalency effects. Surprisingly we find no
evidence of spin on the other apical oxygen O(1) suggesting that the Mn eg
electron distribution along the c-axis is highly anisotropic.
