FIG. 1.

(Color online) The X and Y components (dots) for the bare resonance line measured in vacuum at 4.2 K with a magnetic field B of 840 mT and a drive current amplitude I 0 = 0.47 μA (grounded gate voltage). The resulting displacement amplitude is x 0 = 5.6 nm. Lines are Lorentzian fits, leading to ω 0/2π = 7.067 MHz (position) and Δω/2π = 1.45 kHz (linewidth). Inset: SEM image of the sample with indicated the direction of the static magnetic field (reference trihedron also shown).

FIG. 2.

(Color online) Measurement of the X and Y components (red and blue dots) with a magnetomotive drive of I 0 = 0.93 μA and B = 840 mT in the presence of a gate modulation of frequency ωs  = 2 kHz and voltage Vg 0 = 1.4 V (implying δk/k = 2 × 10−3). The lines are our theoretical predictions.

FIG. 3.

(Color online) Same as Fig. 2 with ωs  = 5 Hz.

Image of FIG. 4.
FIG. 4.

(Color online) Measured (dots) and predicted (lines) heights of the first poles as a function of the modulation frequency ω s/2π with Vg 0 = 1.4 V (other parameters same as Fig. 2).

Image of FIG. 5.
FIG. 5.

(Color online) Measured (dots) and predicted (lines) heights of the first poles as a function of the modulation amplitude Vg 0 with ω s/2π = 1.5 kHz (other parameters same as Fig. 2).
