Abstract
The present invention relates to a logic device including a first and a second arm through which a charging current passes, a channel that connects the arms and includes a first zone of contact with the first arm, and a second zone of contact with the second arm, the arms and the channel being able, in the first zone of contact, to convert a charging current into a spin current and, in the second zone of contact, to convert a spin current into a charging current, and a unit for controlling the direction of the charging current in the second arm, the control unit including a sub-unit for electrical control of a conversion.
Claims16
A logic device comprising:
- a first arm extending along a first direction and letting a charging current flow therethrough;
- a second arm extending along the first direction and letting a charging current flow therethrough;
- a channel connecting said first arm to said second arm, the channel being along a second direction perpendicular to the first direction, the channel comprising three zones, namely:
- a first zone of contact with said first arm, arm;
- a second zone of contact with said second arm;
- and
- a central zone connecting said two zones of contact, said first arm, said second arm and the channel performing a first conversion in said first zone of contact and a second conversion in said second zone of contact, the first conversion being conversion of a charging current flowing through said first arm, into a spin current flowing through the channel, and the second conversion being conversion of a spin current flowing through the channel, into a charging current flowing through said second arm arm;
- and
- a control unit controlling the direction of the charging current flowing in said second arm, the control unit comprising at least one electrical control sub-unit of one of the two conversions.
