The spin polarization in certain organic molecules adsorbed on a magnetic surface depends on how strongly the molecules are bound—a property that could be tailored toward making organic spintronics devices.

Nuclear spins may enable enhanced control of electron spins in quantum information devices.

Ever present fluctuations in semiconductors can be utilized as a demolition-free spectroscopic probe to study ultrafast spin dynamics.

New experiments indicate that the intrinsic regime of the anomalous Hall effect is independent of scattering.

A dual spin valve with antiparallel outer layers is used to demonstrate a new form of current-dependent giant magnetoresistance.

Optical measurements in electron gases at low temperatures and high magnetic fields show the electron spins are, as predicted, polarized, but that this state is surprisingly delicate.

The effects of torques caused by spin-polarized currents are often unwanted in magnetic nanostructures, but they can be diminished with the right design.

From conservation laws to selection rules, symmetry arguments have long been revered for their far-reaching consequences in physics. Now they point to an effective spin-orbit coupling in antiferromagnetic conductors.

The efficient injection of polarized spins from magnetic materials into semiconductors, a prerequisite for spintronics applications, is a formidable challenge. With ferromagnetic Co2FeSi it is now possible to achieve a spin injection efficiency of close to 50%.

Spin decoherence is a fundamental obstacle in quantum computation and spintronics. Scientists show they can increase the lifetime of a localized spin in a diamond lattice up to 100 times by polarizing the surrounding spins on the lattice.
