摘要

Thin films of alpah -Fe_2O_3(0001) (hematite) and gamma -Fe_2O_3 (001) (maghemite) were epitaxially grown on Al_2O_3(0001) and MgO(001) substrates, respectively, using the new molecular beam epitaxy (MBE) system at he Environmental Molecular sciences Laboratory (EMSL). We have investigated the crystalline quality of these films using Rutherford Backscattering (RBS) and channeling expeirments. Minimum yields obtained fromn aligned and random spectra are 2.7+-0.3
