(a) Schematic of the investigated microstructure. Blue depicts the 5.25μm wide Co25Fe75 waveguide, yellow shows the coplanar waveguide (CPW). (b) Micromagnetic simulation of the y-component of the magnetization (black solid line) and of the effective magnetic field Beff,y (red dashed line), both extracted along the width of the waveguide for μ0Hext = 46mT. (c) Hysteresis loop of the waveguide in hard axis direction measured by laser scanning MOKE in the center of the waveguide. (d) Calculated dispersion relation (black solid line) and excitation efficiency of the CPW (red dashed line). (e) BLS intensity measured in a 600MHz window around the excitation frequency frf =9.5 GHz as a function of the excitation power in 1μm distance to the CPW.
