摘要：

Mössbauer spectra of 57Fe-doped polycrystalline CuO/Al 2O3 multilayers (CAOs) show magnetic ordering at liquid helium temperature. The Néel temperature of a CAO with thin CuO layers is lower than that of bulk CuO judged from the temperature dependence of the Mössbauer spectra. A paramagnetic component was observed in all magnetic susceptibility measurements of the multilayers. The component also exists in both polycrystalline and epitaxial CuO/MgO multilayers. We have found that the component was localized at interfaces and derived from the spin fluctuation effect. © 1995 American Institute of Physics.
