The magnetic properties of (111)Cu/Fe multilayers grown on Cu underlayers of several thickness (2000-500-50 angstrom) on cleaved mica have been investigated by Mossbauer spectroscopy and SQUID magnetometry. The analysis of experimental results suggests that 2.5 monolayers of gamma-Fe interfaced with Cu evolves partially from paramagnetic to ferromagnetic states as the Cu underlayer thickness is reduced to 50 angstrom and partially from weak to strong antiferromagnetism.

Abstract
The magnetic properties of (111)Cu/Fe multilayers grown on Cu underlayers of several thickness (2000-500-50 angstrom) on cleaved mica have been investigated by Mossbauer spectroscopy and SQUID magnetometry. The analysis of experimental results suggests that 2.5 monolayers of gamma-Fe interfaced with Cu evolves partially from paramagnetic to ferromagnetic states as the Cu underlayer thickness is reduced to 50 angstrom and partially from weak to strong antiferromagnetism.File in questo prodotto:
