dc.description.abstractIn this thesis, I will analyze and discuss features of spin wave propagation characteristics measured in a one-dimensional (1D) yttrium iron garnet (YIG) magnonic crystal using time-resolved Brillouin light scattering (TR-BLS) measurements. Magnonic crystals are a promising candidate to aid in developing spin-based devices that exploit the spin of the electron since magnonic crystals can be used to control the information transmitted by spin waves. In magnonic crystals, periodic modulation of the material properties is used to create a band structure and hence allow or suppress the propagation of spin waves with specific frequencies. To better understand spin wave propagation in a 1D YIG magnonic crystal, (TR-BLS) measurements were used to map out the temporal and spatial evolution of spin wave pulses at different frequencies. By analyzing the TR-BLS data with a cross-correlation method, the group velocities were determined at different frequencies and a better understanding of the changes in the pulse shape is gained. The TR-BLS data show that multiple width-quantized spin wave modes are present and highlights the importance of considering the two-dimensional nature of spin wave propagation, even in a one-dimensional system.
