Inserting a thin (t*50.5 or 1 nm! layer of the antiferromagnet FeMn into the ‘‘free’’ Permalloy ~Py! layer of a sputtered, current-perpendicular exchange-biased spin valve, Nb/FeMn/Py ~pinned!/Cu/Py ~free!/Nb, is shown to enhance ADR , the difference in specific resistance between the states where the magnetizations of the two Py layers are parallel and antiparallel to each other. Such an incre...
Point-contacts (PC) offer a simple way to create high current densities, 10 A/cm and beyond, without substantial Joule heating. We have shown recently (Nano Letters, 7 (2007) 927) that conductivity of nanosized PCs between a normal and ferromagnetic metals exhibits bi-stable hysteretic states versus both bias current and external magnetic field – the effect typical for spin-valve structures. He...
We propose a spin valve that is based on van der Waals antiferromagnetism and fully electrically controlled. The device composed of two antiferromagnetic terminals allow for vertical bias control linked central scattering potential region. magnetoresistance varies significantly when the orientations in are switched from parallel to antiparallel, because this switch induces mismatch bands same p...
