Evidence for SrHo2O4 and SrDy2O4 as model J1- J2 zigzag chain materials

Neutron diffraction and inelastic spectroscopy is used to characterize the magnetic Hamiltonian of SrHo2O4 and SrDy2O4. Through a detailed computation of the crystal-field levels we find site-dependent anisotropic single-ion magnetism in both materials, and diffraction measurements show the presence of strong one-dimensional spin correlations.Our measurements indicate that competing interactions of the zigzag chain, combinedwith frustrated interchain interactions, play a crucial role in stabilizing spin-liquid type correlations in this series.
