Ultrafast spin-polarized current pulses measured in magnetic layers for the first time - MSNSpin-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 ...
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 ...
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 ...
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 ...
