Spin field effect logic devices

A spin field effect logic device comprising:

• a channel including a magnetic material configured to selectively transmit spin-polarized electrons;
• a source on the channel;
• a gate electrode on the channel;
• a drain electrode configured to output electrons transmitted from the source;
• an output electrode configured to output electrons transmitted from the source;
• a first voltage source connected to the drain;
• a second channel on the channel, the drain on the second channel;
• and
• a second gate electrode on the second channel,
• wherein the source is on the channel,
• the output electrode is connected between the drain and the first voltage source,
• the source and the drain are magnetized in a first direction,
• the gate and the second gate electrodes are configured to control a magnetization state of the channel and the second channel respectively, in order to selectively transmit electrons injected from the source into the channel, and
• the channel and the second channel transmit the spin-polarized electrons which are magnetized in a second direction.
