Preliminary results are presented on the structural and magnetic properties of epitaxial antiferromganetic NiMn and their correlation to the Exchange Bias Effect. Included are x-ray diffraction, reflection and rocking curves of pertinent diffraction peaks. The rocking curves have a FWHM of less than 3∘θ indicating good epitaxial growth of the film. Polarized neutron reflectivity and high angle scattering measurements have been made in order to assess the magnetic properties of the system.
