摘要：

We report the Ni L-2,L-3-edge magnetic circular dichroism (MCD) measurements of ferrimagnetic ZnxNi1-xFe2O4 (x = 0.0, 0.26, 0.50, and 0.75). The Ni MCD asymmetry ratio was found to decrease with increasing x, showing a reduction of the Ni average magnetic moment with Zn content. This observation is interpreted in terms of the variations in the Yafet-Kittel-type canted angles of the Ni moment, giving new insight into the superexchange interactions involving the Ni ions. A comparison with the non-Ni-specific neutron scattering and Mossbauer studies is given.
