THE MOSSBAUER PROPERTIES OF EPITAXIAL FE-BCC NI MULTILAYERS

[摘要] Two series of Fe(110)/[bcc Ni] and Fe(100)/[bcc Ni] heterostructures were grown by molecular beam epitaxy. Analysis of the multilayers with Fe-57 Mossbauer spectroscopy indicated that all of the film's local magnetization directions were oriented in-plane, and revealed that the spectra of both multilayer series consisted of two slightly broadened sextet components, corresponding to interface and interior Fe bilayer sites. The interior sites had slightly enhanced ground state hyperfine field values compared to bulk, while the interfacial sites had reduced ground state hyperfine field values. SQUID magnetometry revealed that the typical film coercivity of the Fe(100)/Ni was approximately an order of magnitude greater than that observed for the Fe(110)/Ni series.
