摘要：
We investigate the transport properties of propagating and nonpropagating exchange modes in a 1D magnonic crystal composed of stacked alternating layers of cobalt (Co) and permalloy (Fe20Ni80). We observe that the exchange magnons excited with energies lying in the energy gap die as soon as the Co layer gets wider.
