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 …

Spintronics is a multidisciplinary field involving physics, chemistry, and engineering, and is a
new research area for solid‐state scientists. A variety of new materials must be found to …

A review of new developments in theoretical and experimental electronic-structure
investigations of half-metallic ferromagnets (HMFs) is presented. Being semiconductors for …

Spintronics refers commonly to phenomena in which the spin of electrons in a solid state
environment plays the determining role. In a more narrow sense spintronics is an emerging …

A broad classification scheme is proposed for half-metallic ferromagnets which embraces
the possibilities of itinerant and localized electrons, as well as semimetallic and …

Half metals, in which one spin channel is conducting while the other is insulating with an
energy gap, are theoretically considered to comprise 100% spin‐polarized conducting …

Abstract Knowledge of the spin polarization is of fundamental importance for the use of a
material in spintronics applications. Here, we used femtosecond optical excitation of half …

We review and critique the recent developments on multifunctional oxide materials, which
are gaining a good deal of interest. Recongnizing that this is a vast area, the focus of this …

Half-metals are defined by an electronic structure, which shows conduction by charge
carriers of one spin direction exclusively. Consequently, the spin polarization of the …

We report an x-ray absorption spectroscopic (XAS) study on thin films of La 0.7 Ce 0.3 MnO
3. The measurements clearly show that the cerium is in the Ce (IV) valence state, and that …
