The first observation of the nuclear Barnett effect

The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular momentum of the electronic ...

Spin devices rev up

Electric currents drive all our electronic devices. The emerging field of spintronics looks to replace electric currents with what are known as spin currents. Researchers from the University of Tokyo have made a breakthrough ...

New insights into magnetic quantum effects in solids

Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3-D pyrochlore Heisenberg model. The surprising ...

Holey graphene as Holy Grail alternative to silicon chips

Graphene, in its regular form, does not offer an alternative to silicon chips for applications in nanoelectronics. It is known for its energy band structure, which leaves no energy gap and no magnetic effects. Graphene antidot ...

Detecting damages in non-magnetic steel through magnetism

Wear, corrosion, material fatigue—these signs of degradation are common to most materials. This makes it all the more important to detect damage early, preferably on the micro-scale. Magnetic test methods are often used ...
