Title: Crystal field levels and magnetic anisotropy in the kagome compounds Nd 3 Sb 3 Mg 2 O 14 , Nd 3 Sb 3 Zn 2 O 14 , and Pr 3 Sb 3 Mg 2 O 14

Here, we report the crystal field levels of several newly discovered rare-earth kagome compounds: Nd 3Sb 3Mg 2O 14, Nd 3Sb 3Zn 2O 14, and Pr 3Sb 3Mg 2O 14. We determine the crystal electric field (CEF) Hamiltonian by fitting to neutron scattering data using a point charge Hamiltonian as an intermediate fitting step. The fitted Hamiltonians accurately reproduce bulk susceptibility measurements, and the results indicate easy-axis ground-state doublets for Nd 3Sb 3Mg 2O 14 and Nd 3Sb 3Zn 2O 14 and a singlet ground state for Pr 3Sb 3Mg 2O 14. These results provide the groundwork for future investigations of these compounds and a template for CEF analysis of other low-symmetry materials.
