    www.dakotamatrix.com/products/21635/haydeeite Haydeeite - Haydeeite is a very rare copper-magnesium hydroxyhalide of the Atacamite group. It has been found only in Chile at three distinct localities, this deposit being the type locality. As you can see from the photos it is a very rich specimen with "Spangolite" blue crystals as singles and cluster.s It is associated with fibrous Atacamite. .

    www.ingentaconnect.com/content/schweiz/njma/2007/00000184/00000001/art00004 Haydeeite was found in the Haydee mine, which is located at the southern end of Salar Grande, Tarapacá Province, northern Chile. It occurs as greenish blue, vitreous, short prismatic, brittle crystals up to 1 mm in size with a perfect cleavage parallel to {0001}. The measured density is 3.27(1) g/cm 3. The mineral is optically uniaxial ...
  • [1503.08023] Haydeeite: a spin-1/2 kagome ferromagnet

    arxiv.org/abs/1503.08023 Abstract: The mineral haydeeite, alpha-MgCu3(OD)6Cl2, is a S=1/2 kagome ferromagnet that displays long-range magnetic order below TC=4.2 K with a strongly reduced moment. Our inelastic neutron scattering data show clear spin-wave excitations that are well described by a Heisenberg Hamiltonian with ferromagnetic nearest-neighbor exchange J1=-38 K and antiferromagnetic exchange Jd=+11 K across ...
