The long‑range magnetic order and underlying spin model in shattuckite Cu5(SiO3)4(OH)2
Original language description
The mineral shattuckite Cu5(SiO3)4(OH)2 is investigated in measurements of X-band electron spin resonance, magnetization and specific heat. The magnetic subsystem of the title compound is constituted by unique combination of well-separated brucite-like corrugated CuO2 layers and CuO2-twisted ribbons. Despite seemingly low-dimensional motives in the structure, shattuckite exhibits properties of three-dimensional antiferromagnet with Weiss/Neel temperatures ratio Θ/TN ~ 2 being weakly ferromagnetic below magnetic ordering temperature TN = 7 K. Tentatively, the spontaneous magnetization appears due to Dzyaloshinskii–Moriya interactions within the brucite-like two-dimensional patterns. The electronic structure calculations suggest strong antiferromagnetic coupling of both edge-sharing and corner-sharing CuO2 units within the layers and weak ferromagnetic coupling of edge-sharing CuO2 units within the ribbons.
