Abstract


  • Here, the interfacial magnetic coupling in an exchange biased [Ni80Fe20/Mn]3

    multilayer system has been studied using polarized neutron re

    ectometry. Previous results on

    this system indicate the importance of the coupling between the Fe-Mn and Ni-Mn orbitals at the

    layer interfaces. Magnetic depth profiles of the multilayer were measured at low temperatures

    under field-cooled and zero-field-cooled conditions. While no definitive interfacial state was

    found, a magnetic moment enhancement of roughly 20-30% in the applied field direction was

    observed throughout the bulk of the NiFe layers in the field-cooled state as compared to the

    zero-field-cooled measurements. The origin of this enhancement also likely stems from Fe-Mn

    and Ni-Mn orbital coupling, but due to the interfacial roughnesses of the sample, the areas

    where this coupling plays an important role is no longer confined to the interface.
