Effect of Annealing on Magnetoresistance in [bcc-Fe (M)/Cu] (M = Co, Ni) Multilayers

Enhanced temperature effect on magnetoresistance in Fe/Mo multilayers

Influence of the interfaces on the anisotropic magnetoresistance of Ni/Co multilayers

All materials exhibit magnetoresistance ~MR!, that is, a change in resistance when a magnetic field is applied. This property is stronger in magnetic than in nonmagnetic materials. Magnetoresistance is a phenomenon of great interest due to its technological applications. Among the different types of MR observed in magnetic materials, the following three should be remarked: anisotropic magnetore...

Superlattice effect in the transport properties of Ni/Co multilayers

The low-temperature transport properties of Ni/Co superlattices were systematically studied. While the resistivity, anisotropic magnetoresistance and anomalous Hall coefficient oscillate as functions of Co and/or Ni layer thicknesses, the ordinary Hall coefficient does not. These oscillations are interpreted as a true superlattice effect, since they disappear when the number of bilayer periods ...

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...

Ternary Ni-Fe-Co Alloys Nanowire Electrodeposition

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...
