Spintronics is one of the emerging research fields in nanotechnology and has been growing
very rapidly. Studies of spintronics were started after the discovery of giant …

This review describes in detail the essential techniques used in microscopic theories on
spintronics. We have investigated the domain wall dynamics induced by an electric current …

The mutual dependence of spin-dependent conduction and magnetization dynamics of
ferromagnets provides the key mechanisms in various spin-dependent phenomena. We …

A self-contained theory of the domain wall dynamics in ferromagnets under finite electric
current is presented. The current has two effects: one is momentum transfer, which is …

We discuss the anomalous Hall effect in a two-dimensional electron gas subject to a
spatially varying magnetization. This topological Hall effect does not require any spin-orbit …

The fabrication methods and physical properties of ordered magnetic nanostructures with
dimensions on the submicron to nanometer scale are reviewed. First, various types of …

In the present-day climate, surface water salinities are low in the western tropical Pacific
Ocean and increase towards the eastern part of the basin. The salinity of surface waters in …

We derive a continuum equation for the magnetization of a conducting ferromagnet in the
presence of a spin-polarized current. Current effects enter in the form of a topological term in …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

The electron transport properties of hybrid ferromagnetic| normal metal structures such as
multilayers and spin valves depend on the relative orientation of the magnetization direction …
