The magnetic structure of the S = 1/2 distorted kagome system clinoatacamite, Cu2Cl(OH)3
The natural mineral clinoatacamite, Cu2Cl(OH)3, has been discussed in the literature as a frustrated quantum spin system. Electronic structure calculations have shown that its monoclinic crystal structure can be read as antiferromagnetic kagome layers, which are coupled ferromagnetically. Studies on clinoatacamite polycrystals have shown that this material undergoes magnetic transitions at 18.1 and 6.4 K. A previous neutron diffraction study on deuterated clinoatacamite powder had revealed magnetic reflections with a propagation vector q = (0, 0, 0). In the past, however, the determination of the magnetic structure of clinoatacamite had led to some difficulties due to the weakness of the Cu magnetic moments and the incoherent scattering from the hydrogen. A magnetic structure was proposed in the literature but without determining the magnetic moment values. Here, a high number of magnetic reflections is required in order to determine precisely the magnitudes of the individual magnetic moments, as there are three Wyckoff positions in clinoatacamite. We therefore propose to carry out a neutron diffraction study using the instrument D10 with three-axis energy analysis.
