Abstract
The spatial-frequency distributions of spin waves in a magnon crystal and their dispersion characteristics have been experimentally investigated. In spite of the weak energy contrast of the crystal, the occurrence of a number of Brillouin zones and the existence of two types of wave nonreciprocity were found: one type is due to the asymmetry of dispersion dependences with respect to the direction of wave propagation, and the second type is due to the different spatial distribution of the wave when it propagates in opposite directions. The magnon crystal made it possible to detect and measure these types of nonreciprocity.
