FIG. 1.

(Color online) Schematic sample design: A Py microstripe (width w s = 2.5 μm, thickness t s = 40 nm, length l s = 75 μm) is placed on top of a Cu waveguide (width w a = 6 μm, thickness t a = 200 nm) which is connected to a microwave generator. The Cu and the Py are separated by an insulation layer (HSQ) (thickness t = 30 nm). As substrate, an oxidized Si sample is used (t Oxide = 200 nm). An alternating current is passed through the Cu waveguide, creating an alternating Oersted field parallel to the externally applied field H ext.

(Color online) (a) Normalized BLS spectrum recorded at an applied external field of μ 0 H ext = 55 mT without applied pumping. (b) Calculated dispersion relations (according to Ref. 15) for the transverse spin-wave modes (0; 1, 2, 3, 8, 9).

FIG. 3.

(Color online) (a) Color coded BLS intensity at f = 6 GHz for different magnetic fields in a range from 30 mT to 70 mT and different applied microwave powers (15-30 dBm). The black dots (i)-(vi) mark the fields and powers at which transverse mode profiles are recorded. (b) Exemplary cut of (a) for a fixed field μ 0 H ext = 54 mT. (c) Calculated wavevectors15 ky for the modes (0; 1, 2, 3, 8) vs. μ 0 H ext for a fixed frequency of 6 GHz.

Individually normalized mode profiles recorded along the stripe short axis (see Fig. 1) at the fields and powers indicated by the black dots in Fig. 3(a).
