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 …

Nanoscience and nanotechnology are tremendously increasing fields of research that aim at
producing, characterizing and understanding nanoobjects and assemblies of nanoobjects …

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 …

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

Nanometer-sized magnetic particles have generated continuous interest since the late
1940s because the study of their properties has proved to be scientifically and …

Spin polarized tunneling studies by Tedrow and Meservey in the early 1970s that showed
the spin conservation in electron tunneling gave rise to the possibility of spin sensitive …

We review recent experimental and theoretical work on ultrasmall metallic grains, ie grains
sufficiently small that the conduction electron energy spectrum becomes discrete. The …

An overview is given of the state of the art in spin electronics. The technical basis is
reviewed and simple ideas of giant magnetoresistance discussed. The connection between …

A theory of spin-transport in hybrid normal metal-ferromagnetic electronic circuits is
developed, taking into account non-collinear spin-accumulation. Spin-transport through …

We study the temperature and bias-voltage dependence of the magnetoresistance (MR) in
insulating Co-Al-O granular films. The MR exhibits strong temperature dependence and is …
