Abstract

We show that magnetic-dipolar-mode oscillations in a normally magnetized ferromagnetic disk have typical atomic properties like discrete-energy levels. Because of the discrete-energy eigenstates of such oscillations resulting from structural confinement, one can describe the oscillating system as a collective motion of quasiparticles - the light magnons. We calculate the energy levels in a magnetic quantum well and the effective masses of the light magnons.
