Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...

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 ...

Physicists discover new type of spin waves

Current technologies for information transfer and processing are challenged by fundamental physical limits. The more powerful they become, the more energy they need, and the more heat is released to the environment. Also, ...

Sending spin waves into an insulating 2-D magnet

Quantum Hall ferromagnets are among the purest magnets in the world—and one of the most difficult to study. These 2-D magnets can only be made in temperatures less than a degree above absolute zero and in high magnetic ...

Researchers successfully demonstrate a quantum gate in silicon

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland have developed a stable quantum gate for two-quantum bit systems made of silicon. ...

Strongly anisotropic spin relaxation observed in graphene

Researchers of the ICN2 Physics and Engineering of Nanodevices Group, led by ICREA Prof. Sergio O. Valenzuela, have unambiguously demonstrated the anisotropic nature of spin relaxation in graphene when interfaced with transition ...
