Giant Magnetoresistance and Interface Structure in Metallic Multilayers

Surfactant-mediated growth of giant magnetoresistance multilayers

A series of experiments have been conducted to evaluate the magnetotransport properties of rf-diode-sputterdeposited giant magnetoresistive multilayers with either copper or copper-silver-gold nonferromagnetic ~NFM! conducting layers. The study revealed that rf-diode-deposited multilayers utilizing Cu80Ag15Au5 as the NFM conducting layer possess significantly superior giant magnetoresistance to...

Calculation of Giant Magnetoresistance in Laterally Confined Multilayers

We have studied the Giant Magnetoresistance (GMR) for laterally confined multilayers, e.g., layers of wires, using the classical Boltzmann equation in the current-in-plane (CIP) geometry. For spin-independent specularity factors at the sides of the wires we find that the GMR due to bulk and surface scattering decreases with lateral confinement. The length scale at which this occurs is of order ...

Giant Magnetoresistance in Magnetic Multilayers Using a New Embossed Surface

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...

Cpp-giant Magnetoresistance and Thermo-electric Power of Multilayers

Oscillations of magnetoresistance and thermo-electric power (TEP ) vs. both nonmagnetic spacer as well as ferromagnetic slab thicknesses are studied in the current-perpendicular-to-plane (CPP ) geometry, in terms of the single-band tight-binding model. The spin-dependent conductance has been calculated from the Kubo formula by means of a recursion Green’s function technique, and the TEP directl...
