The ability to control the propagation of spin waves in magnonic circuits is crucial for further development of magnonic technology [1]. The majority of the existing control mechanisms are based on the use of electrical current [2-4], which is inevitably associated with ubiquitous Ohmic losses and therefore reduced energy efficiency. In this respect, spin-wave control mechanisms utilizing magnetic field and / or inherent micromagnetic memory effects could offer significant benefits to future magnonic technology but are yet to be properly explored [5].
