Query: Magnetochiral Properties of Spin Waves Existing in Nanotubes with Axial
  and Circumferential Magnetization   We report experimental studies of spin-wave excitations in individual 22 nm
thick Ni80Fe20 nanotubes with diameters of about 150 nm by means of Brillouin
light-scattering (BLS) spectroscopy. Irradiated by microwaves we resolve sets
of discrete resonances in the center of nanotubes ranging from 2.5 to 12.5 GHz.
Comparing to a recent theoretical work and micromagnetic simulations, we
identify different characteristic eigenmodes depending on the axial, mixed or
vortex configuration. The mixed and vortex states give rise to modes with
helical phase profiles substantiating an unusual nature of modes attributed to
non-reciprocal spin waves. Our findings provide microscopic insight into
tubular spin-wave nanocavities and magnetochiral effects for 3D nanomagnonics.
