Abstract
Using temperature-dependent measurements of the magneto-optical Kerr effect . (MOKE) we map out a magnetic phase diagram of Fe/Cr(001) superlattices wi th Cr-thicknesses between 10 to 45 Angstrom in a temperature range from 10 to 700 K. By comparison with neutron scattering results, we demonstrate the strong correlation between different magnetic phases of the Cr interlayers and the coupling between the Fe lavers. Mie find an enhancement of the Cr Neel temperature as we reduce the Cr thicknesses, indicating a strong proxi mity effect between the Fe and Cr layers.
