Over the past decade intensive research efforts have been carried out by researchers
around the globe on exploring the effects of dilute doping of magnetic impurities on the …

Dilute magnetic semiconductors and wide gap oxide semiconductors are appealing
materials for magnetooptical devices. From a combinatorial screening approach looking at …

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 …

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

In the last decade after the discovery of" giant magnetoresistance effects" in me tallic
multilayers worldwide developments in basic research and in engineering applications have …

We study spin-dependent electron tunneling in ferromagnetic junctions containing small
metallic islands. The tunneling matrix elements depend on the relative direction of …

In this paper, we present a review of electron transport properties of magnetic granular films.
Magnetic granular films are nanocomposite materials which consist of magnetic …

Spin injection and accumulation are key phenomena supporting a variety of concepts for
spin-electronic devices. These phenomena are expected to be enhanced in nanoparticles …

We have investigated the particle size distributions in Co–Al–O insulating granular films with
various Co concentrations (xCo) by analyzing the superparamagnetic behavior of …
