This review article first presents a summary of current understanding of the magnetic
properties and intrinsic ferromagnetism of transition-metal (TM)-doped ZnO films, which are …

Spin-polarized light sources are a new class of devices in which the radiative recombination
of spin-polarized carriers results in luminescence exhibiting a net circular polarization. The …

In traditional optoelectronic approaches, control over spin, charge, and light requires the use
of both electrical and magnetic fields. In a spin-polarized light-emitting diode (spin-LED) …

We review two strategies for growing ZnO nanowires from zinc salts in aqueous and organic
solvents. Wire arrays with diameters in the nanoscale regime can be grown in an aqueous …

Electrical currents flowing in ferromagnetic materials are spin-polarised as a result of the
spin-dependent band structure. When the spatial direction of the polarisation changes, in a …

Ferromagnetic semiconductors (FMS) enable simultaneous control of both charge and spin
transport of charge carriers, and they have emerged as a class of highly desirable but rare …

A method for the switching of the spin polarization of the electric current injected into a
semiconductor is proposed, based on injecting spins from a diluted magnetic semiconductor …

An overview of X-ray magnetic circular dichroism (XMCD) spectroscopy in the hard X-ray
range is presented. A short historical overview shows how this technique has evolved from …

Materials combining strong ferromagnetism and good semiconducting properties are highly
desirable for spintronic applications (eg, in spin-filtering devices). In this work, we conduct a …

The high-frequency dynamics of spin-polarized carriers and photons in a spin laser have
been studied. The transient response of the device obtained from the rate equations is …
