Three-arm nanostructure: (a) Schematic view where arrows represent magnetization vectors, (b) scanning electron microscope image where darker contrast corresponds to the nonetched conducting areas of the structure.
(Color online) Electrical resistances [(a) and (c)] and [(b) and (d)] measured between terminals of the respective arms AB and AC of the nanostructure as a function of a magnetic field oriented along arm A swept in two opposite directions (differentiated by triangles or circles). The magnetic field direction in (c) and (d) was reversed with respect to cases (a) and (b). The magnitude of “remnant resistance” at zero magnetic field is marked. The resistance was measured applying a probing alternative voltage of about .
(Color online) Electrical resistance measured between terminals of arms B and C of the device as a function of a magnetic field oriented along arm A swept in two opposite directions (differentiated by triangles or circles). The magnetic field direction in the lower plot was reversed with respect to the case of the upper plot. No “remnant resistance” appears.
