Abstract
Periodic multilayered films composed of 1 Å thick Cr and 50 Å thick Sb layers have been prepared by ultra-high vacuum deposition technique. By sequential deposition at 80°C on a Sb(001) buffer layer prepared on a glass and polyimide substrates, a sulerlattice film in which "mono-layers" of NiAs-type inter-metallic compound CrSb are epitaxially grown between Sb layers has been obtained. This superlattice film shows ferromagnetic behavior at 1.7 K although CrSb is antiferromagnetic in the bulk state; however, the ferromagnetic moment is fairly small, 0.2μB/Cr-atom.
