Tuning the spin dynamics of kagome systems — •Dirk Wulferding1, Peter Lemmens1, Hiroyuki Yoshida2, Yoshihiko Okamoto3, and Zenji Hiroi3 — 1IPKM, TU-BS, Braunschweig, Germany — 2NIMS, Tsukuba, Japan — 3ISSP, Tokyo, Japan
Kagome lattice systems are among the most promising candidates for realizing a quantum spin liquid state. We compare the excitation spectra of different kagome compounds and demonstrate that the ground state properties depend critically on the underlying crystal structure.
