N1 - Funding Information:
The research leading to these results has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreements no. 705326, project SWING, and no. 730872, project CALIPSOplus. We acknowledge the support from the Office of Basic Energy Sciences of the US Department of Energy (grant no. DESC0016204), the US Army Research Laboratory and the US Army Research Office (grant no. W911NF-16-1-0113), and the US National Science Foundation. This work was partially performed at Polifab, the micro-and nano-technology center of the Politecnico di Milano. Part of this work was performed at the PolLux (X07DA) endstation of the Swiss Light Source, Paul Scherrer Institut, Villigen, Switzerland. The PolLux endstation was financed by the German Minister für Bildung und Forschung (BMBF) through contracts 05KS4WE1/6 and 05KS7WE1.

N2 - Magnonics is gaining momentum as an emerging technology for information processing. The wave character and Joule heating-free propagation of spin-waves hold promises for highly efficient computing platforms, based on integrated magnonic circuits. The realization of such nanoscale circuitry is crucial, although extremely challenging due to the difficulty of tailoring the nanoscopic magnetic properties with conventional approaches. Here we experimentally realize a nanoscale reconfigurable spin-wave circuitry by using patterned spin-textures. By space and time-resolved scanning transmission X-ray microscopy imaging, we directly visualize the channeling and steering of propagating spin-waves in arbitrarily shaped nanomagnonic waveguides, with no need for external magnetic fields or currents. Furthermore, we demonstrate a prototypic circuit based on two converging nanowaveguides, allowing for the tunable spatial superposition and interference of confined spin-waves modes. This work paves the way to the use of engineered spin-textures as building blocks of spin-wave based computing devices.
