Which phenomenon inhibits spin excitation in a ferromagnet?

💡 Explanation

Dipole-dipole broadening inhibits propagating spin waves, because the local field becomes inhomogeneous, which scatters spin waves and shortens their life; therefore dipole-dipole interactions broaden the line, rather than mechanisms relying on lattice vibrations or domain boundaries.
