Nanostructure of Interfaces and Giant Magnetoresistance of Co/Cu Superlattices

Chuprakov S.A., Verhovsky S.V., Krinitsina T.P., Bannikova N.S., Blinov I.V., Milyaev M.A., Popov V.V., Ustinov V.V., Institute of Metal Physics, RU

The structure, the state of interfaces and magnetoresistance of [Co(1.5nm)/Cu(0.9nm)]n superlattices have been studied. The magnetoresistance decreases with the growth of n from 38% for n = 10 to 24% for n = 40. TEM [...]

Magnetotransport Properties and Tunnel Effect of Thin Film Nano-Structures

Neamtu J., Volmer M., Medianu R.V., National Institute for Research&Development in Electrical Engineering, RO

The investigation of magnetotransport and tunnel effect of magnetic nanostructures plays an important role in design of micro&nanosystems for spintronics. The nano-structures as FM/NM/FM/AFM were deposited by magnetron-sputtering on the oxidized Si wafers, as continuous [...]

Biomolecular diagnostics by a magnetic lab-on-a-chip

Brückl H., Eggeling M., Heer R., Nöhammer C., Schotter J., ARC Seibersdorf Research GmbH, AT

Compared to the established fluorescent labeling method, the use of magnetic markers in biochip sensors has important advantages with respect to the detection of biomolecules at low concentrations. Additionally, the direct availability of an electronic [...]
