“…1(h) -the strongest magnetic reflection, the structurally forbidden (100), is highlighted. Our refinements of the low-temperature ground state do not support the idle-spin model proposed previously [15,16,29], which fails to predict several observed magnetic peaks as shown in the inset to Fig. 1(h).…”

Magnetic frustration, the competition among exchange interactions, often leads to novel magnetic ground states with unique physical properties which can hinge on details of interactions that are otherwise difficult to observe. Such states are particularly interesting when it is possible to tune the balance among the interactions to access multiple types of magnetic order. We present antlerite, Cu3SO4(OH)4, as a potential platform for tuning frustration. The low-temperature magnetic state of its three-leg zigzag ladders is a quasi-one-dimensional analog of the magnetic state recently proposed to exhibit spinon-magnon mixing in botallackite. Density functional theory calculations indicate that antlerite's magnetic ground state is exquisitely sensitive to fine details of the atomic positions, with each chain independently on the cusp of a phase transition, indicating an excellent potential for tunability.

“…This work suggests otherwise, opening up the possibility of the use of a detailed powder work in scrutinising both geological and industrial patina occurrences, in order to suggest conditions under which these and other possible polytypes may be preferentially crystallised. Similar can be said for synthetic forms, where recent work by Vilminot et al (2002, 2006) did not yield single crystals of brochantite, though, in similar hydrothermal syntheses the related sulphate antlerite, Cu 3 (OH) 4 SO 4 , did crystallise in sizes suitable for laboratory single crystal examination.…”

Evidence for the recently described 2M2 polytype of brochantite from X-ray powder diffraction investigation of secondary alteration products of ore material from the Pierre Plate Mine, Vizille, Isère, France is presented. This report is the first to describe the 2M2 polytype from locations outside of Italy and through the use of powder XRD methods. In the procedure used herein, developed in a study by Merlino et al. [Eur. J. Mineral 15, 267–275 (2003)], we have used family reflections, common to both main types of brochantite, as the source of approximate cell parameters from which we obtain positions of characteristic reflections to demonstrate the unique choice of polytype, before final refinement stage. This method demonstrates that the determination of polytype is possible from powder data, for samples typical of both geological and urban environments. Least-squares refined cell parameters for the 2M2 polytype from Pierre Plate are a=12.7409(8) Å, b=9.8371(6) Å, c=6.0109(3) Å, and a=90.135(9)°, constrained in space group P21/n11.

“…It is characterized by three temperatureregions. For T > 50 K, the ZFC-FC susceptibility is reversible and shows a broad maximum centered at 60 K. Below 50 K, there are two bifurcations at 18 with those for Cu(II). The negative h value points to strong and dominant antiferromagnetic interaction.…”

Cu4(OH)6SO4 (1) and Cu4(OD)6SO4 (2) were obtained by hydrothermal syntheses from copper sulfate and sodium hydroxide in H2O and D2O, respectively. They crystallize in the monoclinic system, space group P2(1)/a (14), a = 13.1206(5), b = 9.8551(3), c = 6.0295(2) Angstroms, beta = 103.432(3) degrees, V = 758.3(1) Angstroms(3), Z = 4 and a = 13.1187(5), b = 9.8552(3), c = 6.0293(2) Angstroms, beta = 103.410(3) degrees, V = 758.3(1) Angstroms(3), Z = 4, respectively. They are iso-structural to the mineral brochantite and consist of double chains of edge-sharing copper octahedra that are connected to one another by corners to form corrugated planes along bc; these planes are in-turn bridged by the unprecedented mu7-sulfate tetrahedra to give a 3D-structure. All the hydrogen atoms were precisely located from refinement of the neutron powder diffraction data of the deuterated sample. Magnetic susceptibility data reveal a low-dimensional behavior at high temperature and the presence of both ferromagnetic and antiferromagnetic super-exchanges resulting in a 3D long-range antiferromagnetic ordering at 7.5 K accompanied by a small canting of the moments. The transition is confirmed by a lambda-peak in the specific heat. The magnetic structure at 1.4 K shows the moments are oriented perpendicular to the corrugated planes with alternation along +/-a for neighboring chains within the double chains. The enhanced incoherent scattering at low-angle suggests the existence of short-range ferromagnetic clusters.
