The spin polarization of a single Co monolayer on Cr substrates with
low-Miller indices is investigated using the tight-binding linear
muffin-tin orbital method. For all Cr substrates we consider epitaxial
growth of Co. The Co overlayer is ferromagnetic for the (100) and (111)
faces while for the (110) direction the stable solution is a C(2×2) that
gives a zero net magnetization on the Co monolayer. For (100) Cr substrate
the effect of the Co overlayer is to decrease dramatically the Cr
polarization in the two monolayers underneath the Co and the Co-Cr coupling
at the interface is found ferromagnetic. In the case of the (111) surface
the effect of Co on the magnetization of the Cr substrate is less
pronounced and the Co-Cr coupling is now antiferromagnetic. For the Co
monolayer on the (110) surface we obtain a C(2×2) solution that gives a
zero net magnetization per layer, while for the Co bilayer on Cr(110) we
get a ferromagnetic configuration. In both cases the magnetic moments at
the Cr interface atoms are strongly reduced. ©2000 The American Physical
