Tuning the confinement potential between spinons in the Ising chain CoNb2O6 using longitudinal fields and quantitative determination of the microscopic Hamiltonian: data archive
University of Oxford (2023)
Abstract:
The deposited package contains experimental single crystal inelastic neutron scattering data probing the spin dynamics in the quantum Ising chain magnet CoNb2O6 in longitudinal magnetic field together with corresponding theoretical calculations of the spin dynamics. A matlab script to read and plot all data in ASCII files is also supplied.Negative-chirality order in S = 1/2 kagome antiferromagnet CdCu3(OH)6(NO3)2·H2O

Abstract:
Neutron diffraction and nuclear magnetic resonance (NMR) measurements have been used to analyze the magnetic structure in the S = 1 2 kagome antiferromagnet CdCu 3 ( OH ) 6 ( NO 3 ) 2 ⋅ H 2 O . Below the magnetic ordering temperature T N ≃ 4 K , magnetic Bragg reflections at (101) and (100) were found in the neutron diffraction pattern, which suggests a q = 0 magnetic structure. Furthermore, the vector spin chirality for the q = 0 structure was successfully identified from the internal field direction obtained by the 14 N -NMR measurement, previous magnetization measurements, and magnetic symmetry analysis. Our findings point to a chirality-ordered magnetic structure with negative vector chirality and ⟨ 100 ⟩ anisotropy.Magnetic frustration in a van der Waals metal CeSiI
