NMR Determination of the Low-Field Magnetic Structure of the Cu-Based Mineral Rouaite Cu(OH)NO
Issei Niwata, R. Kumar, Aswathi Mannathanath Chakkingal +5
Frustrated interactions in the Cu-based mineral rouaite with alternating antiferromagnetic and ferromagnetic spin chains, Cu(OH)NO, introduce non-trivial magnetic groun…
Spin-liquid-like ground states in the double hydroxyperovskites CuSn(OD)6 and MnSn(OD)6 evidenced by μSR spectroscopy
Moumita Naskar, Anton A. Kulbakov, Kaushick K. Parui +9
Double hydroxide perovskites with magnetic transition-metal ions were recently identified as a unique class of materials that combine magnetic frustration with correlated proton di…
Spin Liquid Mimicry in the Hydroxide Double Perovskite CuSn(OH) Induced by Correlated Proton Disorder
Anton A. Kulbakov, Ellen HäuÃler, Kaushick K. Parui +13
The face-centered-cubic lattice is composed of edge-sharing tetrahedra, making it a leading candidate host for strongly frustrated magnetism, but relatively few face-centered frust…
Disordered ground state in the three-dimensional face-centred frustrated spin- system MnSn(OH)
Kaushick K. Parui, Anton A. Kulbakov, Ellen HäuÃler +10
Frustrated magnetism in face-centred cubic (fcc) magnetic sublattices remains underexplored but holds considerable potential for exotic magnetic behaviour. Here we report on the cr…
Stacking disorder in novel ABAC-stacked brochantite, CuSO(OH)
Aswathi Mannathanath Chakkingal, Chloe Fuller, Maxim Avdeev +10
In geometrically frustrated magnetic systems, weak interactions or slight changes to the structure can tip the delicate balance of exchange interactions, sending the system into a…
Correlated proton disorder in the crystal structure of the double hydroxide perovskite CuSn(OH)
Anton A. Kulbakov, Ellen HäuÃler, Kaushick K. Parui +8
CuSn(OH) is a quantum spin system from the family of magnetic double perovskite hydroxides, having a frustrated magnetic sublattice. It is also known as the natural mineral mus…
