Spin-current-based devices can therefore operate extremely quickly, currently on time scales of up to one hundred picoseconds. However, the microscopic processes themselves run much faster, in the ...

Researchers have for the first time reported the electrical detection of spin current on topological insulator surfaces at room temperature by employing a ferromagnetic detector.

Because most of the electrons in this current have their spins pointing in a single direction, this current is spin-polarized. Controlling direction and polarization.

"Our devices generate a spin-polarized current flowing on the surface of a topological insulator. They can be used as a current source for spintronic devices, which use electron spin to transmit ...

Aspin-polarized electron current can apply a torque on the local magnetization of a ferromagnet. This spin-transfer effect 1,2 provides a new method for manipulating magnetic systems at the ...

Spin-polarized current is a charge current with an uneven distribution of electron spin directions – that is, different numbers of up spin and down spin electrons. “Our method is an important ...

Spin current on topological insulator detected electrically at room temperature. Chalmers University of Technology. Journal Nano Letters Funder EU Marie Curie Career Integration Grant, Swedish ...

When circular polarized light is irradiated onto a thallium lead alloy, the majority “up spins” of electrons flow in the right direction (spin-polarized current). Researchers Ibuki Taniuchi ...

Physicists in Japan have discovered a new way to create spin-polarized currents of electrons by simply heating one end of a magnetic sheet. The team was able to make a spin current in the sheet flow 6 ...
