Spin-Singlet Ground State of Two-Dimensional Quantum Spin Antiferromagnet (CuCl)Ca2Nb3O10
Abstract
We report structural and magnetic properties of the triple-layered perovskite (CuCl)Ca2Nb3O10 with a spin-1/2 CuCl layer, investigated by transmission electron microscopy, magnetic susceptibility, high-field magnetization, specific heat, µSR, and inelastic neutron scattering measurements. The results show that (CuCl)Ca2Nb3O10 has a spin-singlet ground state with a gap of Δ/kB = 11 K. The observation of a 2 × 2 superstructure suggests a coherent …
