摘要：
We have studied physical properties of MnAs thin films grown by Molecular-Beam Epitaxy as well as their postgrowth annealing effects. The samples grown at 600 degrees C show the preferred crystal orientation of type-B independent of substrate whereas type-A is observed for the samples grown at below 200 degrees C. The sample grown at 600 degrees C on GaAs(001) substrate is magnetized to only one direction even on the easy axis of magnetization. The magnetic properties are vastly enhanced after post- growth annealing for both MnAs/Si(001) sample with no ferromagnetism and ferromagnetic MnAs/GaAs(001) grown at 200 degrees C.
