Received 21 November 1997

Epitaxial growth of Co on GaAs(001) and its in-plane magnetic anisotropy
are studied using reflection high-energy electron diffraction, a
high-resolution transmission electron microscope, and the magneto-optical
Kerr effect. In the initial and final stages of growth, Co exists in
single-crystalline body-centered-cubic (bcc) and hexagonal-closed-packed
(hcp) phases, respectively, while in the middle stage the coexistence of
the bcc and hcp structures is observed. For the bcc Co thin films on
GaAs(001), a fourfold in-plane magnetic anisotropy with easy axes along the
<100> directions is realized and discussed.
