This chapter discusses the spin-transfer effect, which is described as the transfer of the spin angular momentum between the conduction electrons and the magnetization of the ferromagnet that occurs due to the conservation of the spin angular momentum. L. Berger, who introduced the concept in 1984, considered the exchange interaction between the conduction electron and the localized magnetic moment, and predicted that a magnetic domain wall can be moved by flowing the spin current. The spin-transfer effect was brought into the limelight by the progress in microfabrication techniques and the discovery of the giant magnetoresistance effect in magnetic multilayers. Berger, at the same time, separately studied the spin-transfer torque in a system similar to Slonczewski’s magnetic multilayered system and predicted spontaneous magnetization precession.

Several possibilities of “engineering” low-dimensional solids on the atomic scale are discussed. The electronic and magnetic structure of such materials is explored for two classes, i.e., multilayers and “wires” attached to step edges. Magnetic multilayers represent a particularly promising case, since quantum effects have macroscopic consequences. Quantization perpendicular to the layers is connected with oscillatory magnetic coupling, which in turn is important for obtaining “giant” magnetoresistance. This effect is being applied towards the fabrication of magnetoresistive reading heads for magnetically stored data. Extensions towards lateral superlattices and quantum wires are explored, where a stepped surface acts as a template. It is found that electrons can be trapped at step edges, and level shifts of the order 0.5 eV are observed for atoms adsorbed at step edges.
