Magnetization dynamics in pairs of submicrometer-sized permalloy rectangles are studied by means of broadband-ferromagnetic resonance measurements. The coupling strength of neighboring elements depends on their center-to-center distance. The stray field of one rectangle decreases the local effective field at the position of the other rectangle. Pairs consisting of two different rectangles, like in a conventional all-metal lateral spin-valve device, are studied. Moreover, the cone angles of the precessional motion of the magnetization at ferromagnetic resonance are determined using transport measurements. Large cone angles of up to 13.7 degrees are realized in a sample geometry that permits electrical insulation together with a small distance between the permalloy rectangles and the exciting coplanar waveguide.
