dc.description.abstract | We have used the method of Wannier functions to calculate the frequencies and profiles of spin
waves localised in one-dimensional (1D) magnonic crystals due to a gradient in the bias magnetic
field. This localisation of spin waves is analogous to the phenomenon of Bloch oscillations of
quantum-mechanical electrons in crystals in a uniform electric field. As a convenient yet realistic
model, we consider backward volume magnetostatic spin waves (BVMSWs) in a film of yttriumiron garnet (YIG) in a bias magnetic field comprising spatially uniform, cosine and gradient
contributions. The spin-wave spectrum is shown to have the characteristic form of a WannierStark ladder. The analytical results are verified using those obtained using numerical
micromagnetic simulations. The physics of spin-wave Bloch oscillations combines the topics of
magnonic crystals and graded magnonic index – the two cornerstones of modern magnonics. | en_GB |
