Enhanced temperature effect on magnetoresistance in Fe/Mo multilayers

Giant magnetoresistance in Co/Cu multilayers sputtered with Kr

The critical condition for the giant magnetoresistance (GMR) effect has not yet been fully clarified. Reports on the MR ratio of C o / C u multilayers (MLs) disagree as to whether the interfacial roughness or crystallinity of the MLs is the cause. The film morphology is significantly affected by sputtering conditions such as sputtering gas and pressure. This paper presents some results of the m...

Magnetic Depth Profiling Co/Cu Multilayers to Investigate Magnetoresistance

The magnetic microstructure responsible for the metastable high resistance state of weakly coupled, as-prepared [Co(6nm)/Cu(6nm)]20 multilayers was analyzed using polarized neutron reflectivity (PNR) and scanning electron microscopy with polarization analysis (SEMPA). This paper focuses and expands on the SEMPA measurements. In multilayer structures such as these, SEMPA can be combined with ion...

Magnetic interactions and interface properties in Co/Fe multilayers

Co/Fe multilayers with different layer thickness formed by electron beam evaporation in ultrahigh vacuum have been investigated by grazing incidence x-ray reflectivity ͑GIXRR͒ and alternating gradient force magnetometry. The interface thicknesses are lower than GIXRR uncertainty ͑ϳ1 nm͒, favoring a strong magnetic exchange interaction between the layers responsible for their single phase magnetic b...

Correlation effects in Co / Cu and Fe / Cr magnetic multilayers

The electronic structure of Co/Cu(001) and Fe/Cr(001) magnetic multilayers has been investigated within the local density approximation combined with dynamical mean field theory. Our calculation shows enhanced density of states at the Fermi level, suggesting that electronic correlations might play an important role in the transport properties of multilayers.
