A new scheme exploiting the orbital rather than the spin degree of freedom allows for studying the Kondo effect without disturbing it.

Short chains of iron atoms deposited on a metal surface could be used to transmit bits of magnetic information.

The coupling of single spins with mechanical oscillators should lead to superior nanodevices that rely on magnetism.

Theorists propose a mechanism to induce domain-wall motion in ferromagnetic nanowires that may lead to unprecedented speeds.

Optical tuning of resonant NMR frequencies of nuclear spins in a single quantum dot achieves spatial resolution below the size of the dot.

A robust measurement scheme indicates that a spin-related torque that speeds up moving domain walls in magnetic nanostructures is larger than previously estimated.

A microscopic study of magnetic nanoislands on a surface challenges the widely held view that all atoms in a relaxing nanoparticle flip their spins in unison.

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.

If a magnet is small enough, an electric current carrying polarized spins can flip it around. Scientists are finding clever ways to control this spin-torque effect precisely, both for when it is wanted and when it is not.
