1 Chiral Coupling to Magnetodipolar Radiation
21
Magnons can interact remotely by their chiral dipolar magnetic fields with other
quasiparticles including other magnons, photons, phonons, and conduction electron
spins. Strong chiral coupling between magnons and photons exist, e.g., in microwave
waveguides or cavities that contain chains of small magnets on special lines [9, 10].
Large magnon numbers accumulate at one edge of a chain of magnets when excited
by local antennas [9, 10]. Spin currents by electrons or phonons may be generated by
the chiral magnetodipolar radiation as well. Chirality is a functionality that has not
yet been employed much in spintronics, but could be the basis for a new generation
of spin-based devices made from conventional materials.
