| contents | We report an experimental study of spin wave modes in individual cylindrical nanowires, a textbook situation of confined spin waves in 3D nanomagnetism. We observe discrete modes of thermal spin waves with micro-Brillouin light scattering, whose frequencies $f$ shift to higher values as the applied longitudinal induction magnetic field $B_z$ increases. Micromagnetic simulations allowed us to associate every $f(B_z)$ curve to a given spatial mode, labeled with radial and azimuthal indices $\ell$ and $m$. |
