Theory of giant magnetoresistance in magnetic granular films
TLDR
In this paper, a spin-dependent scattering model was proposed to explain various features of the magnetoresistance and to predict new features, and the model was further extended to include the temperature dependence.Abstract:
It has been recently found that giant magnetoresistance can also be obtained in metallic films containing magnetic particles. Based on spin‐dependent scattering, we propose a model that allows us to explain various features of the magnetoresistance and to predict new features. The model is further extended to include the temperature dependence of the magnetoresistance.read more

TL;DR: Giant magnetoresistance in heterogeneous thin film Cu-Co alloys consisting of ultrafine Co-rich precipitate particles in a Cu-rich matrix is observed, modeled by including spin-dependent scattering at the interfaces between the particles and the matrix, as well as the spin- dependent scattering in the Co- rich particles.

Electrical conductivity of magnetic multilayered structures
TL;DR: The electrical transport properties of magnetic multilayered structures are dominated by three ingredients: the scattering within layers that changes from one layer to another, the additional scattering resistivity due to the roughness of the interfaces between layers, and the resistivity that depends on the orientation of the magnetization of the magnetic layers as discussed by the authors.
