Image of FIG. 1.
FIG. 1.

(Color online) Schematic illustrations of (a) nonlocal spin injection and (b) local spin injection.

Image of FIG. 2.
FIG. 2.

(a) SEM image of the fabricated lateral spin-injection device and (b) magnified image around the Py particle.

Image of FIG. 3.
FIG. 3.

(Color online) Nonlocal spin-valve signal measured at 77 K with current excitation on the right-hand side (a) and on the left-hand side (b) together with corresponding schematic probe configurations.

Image of FIG. 4.
FIG. 4.

(Color online) The NLSV signal measured after the pulsed nonlocal spin current injection as a function of the current amplitude with different probe configurations excited by the pulsed current applied on the right-hand side (a) and on the left-hand side (b).

Image of FIG. 5.
FIG. 5.

(Color online) Schematic illustrations of (a) the induced chemical potential for the negative current injection in the antiparallel configuration and (b) that for the positive current injection in the parallel configuration. (c) Spin-dependent chemical potential inside the Py particle in parallel (antiparallel) to the Py pad in the negative current. The direction of the injected spin current depends on the polarity of the current and does not depend on the magnetization configuration between the Py pad and the particle.
