  In this work, we comprehensively investigate and discuss the structural,
magnetostatic, dynamic, and magnetoresistive properties of epitaxial Co/Mo
superlattices. The magnetization of the Co sublayers is coupled
antiferromagnetically with a strength that depends on the thickness of the
nonmagnetic Mo spacer. The magnetization and magnetoresistance hysteresis loops
clearly reflect interlayer exchange coupling and the occurrence of uniaxial
magnetic anisotropy induced by the strained Co sublayers. Upon accounting for a
deviation of the sublayer thicknesses from the nominal value, theoretical
modeling, including both micromagnetic and macrospin approaches, precisely
reproduces experimental magnetic hysteresis loops, magnetoresistance curves,
and ferromagnetic resonance dispersion relations. The Mo spacer thickness as a
function of the interlayer magnetic coupling is determined as a fitting
parameter by modeling the experimental results.
