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 …

Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

Magnetic sensors can be classified according to whether they measure the total magnetic
field or the vector components of the magnetic field. The techniques used to produce both …

Some of the most relevant finite-size and surface effects in the magnetic and transport
properties of magnetic fine particles and granular solids are reviewed. The stability of the …

Using remarkably simple experimental techniques it is possible to gently break a metallic
contact and thus form conducting nanowires. During the last stages of the pulling a neck …

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 …

The phenomenon of electron tunnelling has been known since the advent of quantum
mechanics, but continues to enrich our understanding of many fields of physics, as well as …

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 …

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 perovskite manganites with generic formula RE 1− x AE x MnO 3 (RE= rare earth, AE=
Ca, Sr, Ba and Pb) have drawn considerable attention, especially following the discovery of …
