摘要：

Cr/Sb multilayered films take two types of structures - epitaxial superlattice and non-epitaxial multilayer - depending on the thickness of Cr layer (d(Cr)) and substrate temperature during deposition (T(S)). The epitaxial superlattices were formed when d(Cr) less-than-or-equal-to 2 angstrom and T(S) = 90-degrees-C; CT and Sb reacted into a NiAs-type compound CrSb, and furthermore deposited Sb grew epitaxially on the CrSb layer. With other deposition parameters, non-epitaxial Cr/Sb multilayers were formed, in which Cr layers are polycrystalline or amorphous-like but Sb layers are crystalline and [00.1] oriented. The reactivities of Cr/Sb interfaces greatly affect the film quality. Magnetic properties are also dependent on the degree of compound formation. The epitaxial CrSb/Sb superlattices show a ferromagnetic feature at 5 K, whereas the non-epitaxial Cr/Sb multilayers show a paramagnetic feature.
