Abstract

Single crystal neutron diffraction studies have been performed on the S = {3/2} kagome staircase compound Co3V2O8 with a magnetic field applied along the magnetization easy-axis (H || a). Previous zero field measurements [Y. Chen, et al., Phys. Rev. B 74, 014430 (2006)] reported a rich magnetic phase diagram, with a ferromagnetic ground state as well as incommensurate, transversely polarized spin density wave (SDW) phases (with a propagation vector of k = (0 δ 0)) interspersed with multiple commensurate lock-in transitions. The magnetic phase diagram with H || a adds further complexity. For small applied fields, υ0H ≅ 0.05 T, the commensurate lock-in phases are destabilized in favor of the incommensurate SDW, while slightly larger applied fields restore the commensurate lock-in phase with δ= 1⁄2 and yield a new commensurate phase with δ = {2/5}. For all measurements in an applied field, higher-order scattering is observed that corresponds to the second-harmonic.
