Spintronic circuit and method of operation therefore

摘要

The invention relates to a spintronic circuit (10; 11; 15) comprising:
- a conductive non-magnetic channel (1);
- means (2, NM, FM1-FM3) for generating spin polarized electrons (4) in the non-magnetic channel (1) by spin extraction;
- at least two ferromagnetic contacts (FM1-FM3) arranged along the non-magnetic channel (1) one after another,
- means (7, 8, 9) for adjusting the magnetization direction of the ferromagnetic contacts (FM1-FM3);
- means for propagating the spin polarized electrons (4) along the non-magnetic channel (1);
- means (5, 6) for measuring the contact resistance of the individual ferromagnetic contacts (FM1-FM3), wherein the contact resistance depends on the relative alignment of the spin polarization direction of the spin polarized electrons (4) in the non-magnetic channel (1) at the ferromagnetic contact (FM1-FM3) and the magnetization direction of the ferromagnetic contact (FM1-FM3).
