One hundred and one years after JJ Thomson was awarded the Nobel Prize for the
discovery of the electron, the 2007 Nobel Prize for Physics was awarded to Professors Peter …

Publisher Summary This chapter discusses the physics of giant magneto resistance (GMR).
The chapter emphasizes the role of the spin-polarized electronic band structure that is …

A quasi one-dimensional model of spin transport in heterogeneous media based on the
Boltzmann equation is presented in order to define the basic properties characterizing …

Publisher Summary Magnetoresistance (MR) is the change in electrical resistance of a
material in response to a magnetic field. All metals have an inherent, albeit small, MR owing …

We examine the quantum and semiclassical approaches to the calculation of the electrical
conductivity using a model of free electrons with a finite lifetime. We evaluate the Kubo …

We show that the Kubo formula can be used to calculate the nonlocal electrical conductivity
of layered systems from first principles. We use the layer Korringa-Kohn-Rostoker method to …

Giant magnetoresistance has been observed in both magnetic multilayers and magnetic
granular solids. We develop a framework for unifying these particular realizations of …

The linear transport behavior of metallic multilayers is studied by using the real-space Kubo
formula, for a model Hamiltonian consisting of zero-range spin-dependent impurity …

We present measurements of the conductance and magnetoconductance as a function of
cobalt layer thickness for cobalt-copper-cobalt spin valves deposited by magnetron …

A theory of the electrical conductivity of homogeneous random alloys based on the Korringa—
Kohn—Rostoker coherent potential approximation (KKR‐CPA) is generalized to treat an …
