We present the topology of magnons on triangular kagome lattice (TKL) by calculating its Berry curvature, Chern number, and edge states. In addition to ferromagnetic state, TKL hosts ferrimagnetic ground state as two sublattices can couple with each other either ferromagnetically or antiferromagnetically. Using Holstein-Primakoff (HP) boson theory Green's function approach, we find that has a r...
