Spin-wave integrated circuit using magnetic garnet films attract many interests because of their low Joule heating as well as the wide range of tunability of the wavelength. In this circuit, the phase interference of spin waves plays an important role to show functions. Hence, the control of phase and magnitude of spin waves is an essential technique to realize spin-wave integrated circuits. To control the phase and magnitude of spin waves, we fabricated magnonic crystals using metal periodic structures fabricated on magnetic garnet films. Forward volume spin waves propagated through the magnonic crystal and showed a magnonic bandgap. In this paper, the designing of the magnonic crystal using finite integration technique (FIT) and fabrication of samples using etching were also described.
