摘要：

We have grown. a 37-period GaSb(25 angstrom)/MnSb(2 angstrom) superiattice on GaAs(001) substrate with 1000 A GaSb buffer layer by solid-source molecular beam epitaxy. We have observed that the streaky RHEED patterns of GaSb and MnSb were maintained even when the growth was finished in 37 periods, indicating the 2-dimensional layer-by-layer growth of MnSb on GaSb or vice versa. Interestingly, a GaSb(25 angstrom)/NlnSb(2 angstrom) superlattice showed ferromagnetic ordering up to above 400 K with its coercive field of 380 Oe at 10 K.
