چکیده
We report unidirectional transmission of micron-wide spin waves beams in a 55 nm thin YIG. downscaled chiral coupling technique implementing Ni 80 Fe 20 nanowires arrays with different widths and lattice spacing to study the non-reciprocal exchange down λ ≈ nm. A full wave spectroscopy analysis these high wavevector coupled-modes shows some difficulties characterize their propagation properties, due both non-monotonous field dependence efficiency, also inhomogeneous stray from nanowires.

Microwave excitation of spin wave beams in thin ferromagnetic films.
An inherent element of research and applications in photonics is a beam of light. In magnonics, which is the magnetic counterpart of photonics, where spin waves are used instead of electromagnetic waves to transmit and process information, the lack of a beam source limits exploration. Here, we present an approach enabling generation of narrow spin wave beams in thin homogeneous nanosized ferrom...
متن کاملNon-reciprocal flexural wave propagation in a modulated metabeam
Flexural wave propagation in an Euler–Bernoulli beam coupled to a set of spring–mass resonators is investigated in the presence of a pump wave in the form of a space–time modulation of the beamresonators coupling stiffness. A phase matching condition implies then that waves incident along or against the pump wave behave differently and gives rise in select frequency bands to one-way blocking an...
متن کاملModulated phononic crystals: Non-reciprocal wave propagation and Willis materials
Research on breaking time-reversal symmetry in wave phenomena is a growing area of interest in the field of phononic crystals and metamaterials aiming to realize one-way propagation devices which have many potential technological applications. Here we investigate wave propagation in phononic crystals, periodic laminates in particular, where both elastic moduli and mass density are modulated in ...
متن کاملNon-reciprocal wave propagation in modulated elastic metamaterials.
Time-reversal symmetry for elastic wave propagation breaks down in a resonant mass-in-mass lattice whose inner-stiffness is weakly modulated in space and in time in a wave-like fashion. Specifically, one-way wave transmission, conversion and amplification as well as unidirectional wave blocking are demonstrated analytically through an asymptotic analysis based on coupled mode theory and numeric...
