determined with good precision using spherical neutron polarimetry. The determined total moment associatedwith each Cr 3+ ion is only 2.48 μB rather than the predicted 2.97 μB. The loss of moment can be attributed ... attributed to covalent mixing of the Cr 3d electrons with O 2p orbitals in π-type antibonding orbitals. Positive and negative spin ...
