Abstract

In a recent publication Moodera and Meservey concluded from their diffraction data that thin Bi films deposited on a Ni buffer layer have the fcc structure. We point out that the observed diffraction pattern can also be assigned to the common rhombohedral phase with a (102) orientation with respect to the surface.
