a, Representative BLS spectra showing FMR and the auto-oscillations measured at Id.c. = 0.40, 0.50 and 0.80 mA. b, Current-dependent auto-oscillation signal measured using μ-BLS. The solid vertical lines refer to the current values at which BLS spatial maps (c–e) are taken. c–e, SW intensity profiles of the double SHNOs along the constrictions, measured at applied current Id.c. = 0.4 mA (c), 0.5 mA (d) and 0.75 mA (e). The dashed lines indicate the positions of the constrictions.
