SUMMARY
Magnetostatic spin waves, also known as magnons, are collective excitations in a ferromagnetic medium where spins are aligned in the ground state but become misaligned in an excited state. These waves arise due to the interaction between neighboring spins, leading to wave-like behavior similar to phonons in lattice vibrations. The discussion highlights the relationship between spin waves and solitons, emphasizing the complexity of excitations in ferromagnetic materials.
