Magnetic domain studies, Brillouin scattering experiments and microwav
e spectroscopy were performed on Co/Cr/Co trilayers. For d(Cr) < 10 An
gstrom, strong ferromagnetic coupling is found, while above 10 Angstro
m of Cr the interlayer coupling is negligible. In ultra high vacuum de
posited samples with d(Cr) about 15 Angstrom, an antiferromagnetic cou
pling was found (K-c approximate to -0.1 erg/cm(2)), accompanied by a
transition to a patch domain pattern.
