(Color online) Scanning electron micrograph of the sample.

FIG. 2.

(Color online) (a) Resonant curve for the fundamental mode of the Py dot measured at P = 100 µW (symbols) and a Lorentzian fit of the data (curve). (b) A 1100 by 600 nm spatial map of the BLS intensity obtained at resonant excitation frequency f 0 = 9.3 GHz. The map was recorded with the spatial step size of 50 nm. (c) Same as (b), at non-resonant excitation frequency f = 5 GHz. (d) BLS intensity vs excitation power recorded at two frequencies far below f 0, as labelled. Lines are linear fits to the data.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Intensity of the second harmonic vs its frequency. Curves are Lorentzian fits of the resonant peaks. (b) Spatial map of the BLS intensity recorded by exciting the dot at the frequency f = 5.1 GHz and detecting the BLS signal at the frequency 2f = 10.2 GHz, at the excitation power P = 50 mW. (c) Same as (b), for f = 4.55 GHz, 2f = 9.1 GHz. (d) The intensity of the second harmonic I 2f vs the intensity I f of directly excited magnetization oscillations at two resonant excitation frequencies, as labelled. Lines are quadratic fits to the data I 2f = aI f 2.

Image of FIG. 4.
FIG. 4.

(Color online) (a) Intensity of the third harmonic vs its frequency (symbols) and the Lorentzian fit of the resonant peak (curve). (b) Spatial map of the BLS intensity recorded by exciting the dot at the frequency f = 3.1 GHz and detecting the BLS signal at the frequency 3f = 9.3 GHz, at the excitation power P = 50 mW. (d) The intensity of the third harmonic I 3f vs the intensity I f of the directly excited magnetization oscillations, at f = 3.1 GHz. Solid line is a fit to the data with I 3f  = aI f 3. Dashed line marks the boundary I 3f = I f.
