Ultra-high-vacuum electron-beam-evaporated Co/Fe multilayers (C-x/Fe-3x with x = 5, 10, 15 nm) were studied by atomic and magnetic force microscopy (AFM, MFM), vibrating sample magnetometry (VSM) and conversion electron Mossbauer spectroscopy (CEMS). MFM investigation showed long, dense and parallel domain regions (stripe domains) with the average width decreasing with the multilayer thickness. VSM and CEMS measurements showed the presence of an out-of-plane anisotropy, whose origin is ascribed to a planar stress at the interfaces, and which can give account of the observed narrow stripe domain pattern.

Abstract
Ultra-high-vacuum electron-beam-evaporated Co/Fe multilayers (C-x/Fe-3x with x = 5, 10, 15 nm) were studied by atomic and magnetic force microscopy (AFM, MFM), vibrating sample magnetometry (VSM) and conversion electron Mossbauer spectroscopy (CEMS). MFM investigation showed long, dense and parallel domain regions (stripe domains) with the average width decreasing with the multilayer thickness. VSM and CEMS measurements showed the presence of an out-of-plane anisotropy, whose origin is ascribed to a planar stress at the interfaces, and which can give account of the observed narrow stripe domain pattern.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
