Abstract
We discuss the realization of a magnonic version of the STImulated-Raman-Adiabatic-Passage (m-STIRAP) mechanism using micromagnetic simulations. We consider the propagation of magnons in curved magnonic directional couplers. Our results demonstrate that quantum-classical analogy phenomena are accessible in magnonics. Specifically, the inherent advantages of the STIRAP mechanism, associated with dark states, can now be utilized in magnonics. Applications of this effect for future magnonic device functionalities and designs are discussed.
Highlights
In analogy to photonics, the field of magnonics aims at the use of spin waves and their quanta, the magnons.[2,3,4,5] Spin waves are the collective excitations of a magnetically ordered solid

Summary
The field of magnonics aims at the use of spin waves and their quanta, the magnons.[2,3,4,5] Spin waves are the collective excitations of a magnetically ordered solid. If both modes are excited at the working frequency, the coherent interference of them leads to a periodic beating of the spin-wave energy from one waveguide to the other with a characteristic coupling length L.
