SW parameter in magnetic multilayers with rough interface

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...

Spin-Dependent Interface Transmission and Reflection in Magnetic Multilayers

First-principles calculations of transmission and reflection from Ag/Fe, Au/Fe, Cu/Co, and Cu/Ni interfaces show very strong spin dependence that differs significantly from expectations based on free electron approximations. The results can be used to understand both the giant magnetoresistance and the oscillatory exchange coupling observed in magnetic multilayers of these materials. The spin d...

Interface alloying and magnetic properties of Fe/Rh multilayers

Multi-Reaction and Scattering from Rough Multilayers

This paper demonstrates how the evaluation of the electromagnetic scattering from 3D rough multilayers can be analytically conducted in the framework of the Volumetric Perturbative Reciprocal Theory (VPRT). The advantage of the proposed approach is twofold. Indeed, in this framework the pertinent closed-form (first-order) scattering solution is derived in a conceptually clean way and is directl...

Interface Synthesis in Embedded HW/SW Systems

Since several years, embedded systems are used in an expanding number of domains. Furthermore, their complexity has significantly increased and most embedded systems must respect several design constraints. Hence, it becomes necessary to introduce major improvements in CAD methodologies in order to help designers. Hardware-Software codesign attempts to deduce automatically heterogeneous system ...
