Abstract

Magnetic media with artificial periodic modulation—magnonic crystals (MCs)—enable tunable spin-wave dynamics and band structure engineering. Nanoscaling enhances these capabilities, making magnonic nanocrystals promising for both fundamental studies and applications. Here, we report on the design, fabrication, and characterization of one-dimensional YIG MCs with nanoholes ( d ≈ 150 nm) spaced a ≈ 1 μm apart. Microfocused Brillouin light scattering and propagating spin-wave spectroscopy, supported by TetraX and MuMax³ simulations, reveal spin-wave transmission over 5 μ m in the Damon-Eshbach configuration and the formation of pronounced bandgaps with rejection levels up to 26 dB. Detailed analysis of the spin-wave dispersion uncovered complex mode interactions, including two prominent anticrossings at 3.1 and 18.7 rad/ μm , between which the spin-wave energy is predominantly carried by the n = 2 mode, enabling efficient transmission. The results advance the development of functional MCs and open pathways toward 2D magnonic nanoarrays and magnonic RF nanodevices.
