Interlayer magnetic coupling in epitaxial Fe/Cr(211) and (100) superlattices
Technical Report
·
OSTI ID:10194459
The authors present magnetic characterization of epitaxial Fe/Cr(211) and Fe/Cr(100) superlattices grown simultaneously on MgO(110) and (100) substrates, respectively. At room temperature, the coupling for these two orientations oscillates in sign with the same period (18{angstrom}), phase and strength. These results indicate that the long-period oscillation is independent of the nested feature of the Cr Fermi-surface. They examine the temperature dependence of interlayer coupling and find a uniform AF bias develops in the (211) samples upon cooling and observe strongly temperature-dependent biquadratic coupling in the (100) samples.
