Figure 5
(a–e) AMR loops in the FeCoB nanostrip with the field applied in the y-axis (see Fig. 1a), for increasing power of the SAW as indicated. The loops are measured with de DC current of − 100 µA following the geometry displayed in Fig. 1a. Note the increase in the total resistance when the power of the SAW increases and the large asymmetry generated for large power of the SAW. (f) Shows the lock-in measurement in the FeCoB nanostrip following the set-up described in Fig. 3a but with the external field applied along the y-axis. (g) Shows the lock-in measurement in the Ni nanostripe with the external field along the y-axis (see complete set of measurements in Suppl. Info. S5).
