Effects of exchange distortions and spin rotation on the spin dynamics of the magnetic Kagome lattice

ORAL

Abstract

In this talk, we examine the effect of distorted magnetic interactions in the Kagome lattice on the spin-wave dynamics. Using a Holstein-Primakoff expansion of the Heisenberg Hamiltonian, we determine the analytical solutions for the various magnetic configurations on the Kagome lattice. Through an understanding of the magnetic phase diagram, we characterize the changes in the spin-waves of the standard magnetic configurations with variable exchange interactions as well as examine the rotation and evolution of the 120 degree phase. The goal of this work is to gain a general understanding of the magnetic fingerprint for these configurations for experimental methods and identification.
