“…One such lattice that has increased in popularity is the Kagome lattice, which is described as a two-dimensional triangular three-sublattice structure and the foundational structure for the three-dimensional pyrochlore lattice [14][15][16][17]. This extra sublattice helps distinguish the Kagome from the two-sublattice honeycomb lattice [18].…”

This study examines the effect of distorted triangular magnetic interactions in the Kagome lattice. Using a Holstein-Primakoff expansion, we determine the analytical solutions for classical energies and the spin-wave modes for various magnetic configurations. By understanding the magnetic phase diagram, we characterize the changes in the spin waves and examine the spin distortions of the ferromagnetic (FM), Antiferrimagnetic (AfM), and 120 • phases that are produced by variable exchange interactions and lead to various non-collinear phases, which provides a deeper understanding of the magnetic fingerprints of these configurations for experimental characterization and identification.
