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…

Physical properties of new delafossite triangular-lattice compounds TlErSe and TlTmSe

Bastian Rubrecht, Ellen Häußler, Mirtha Pillaca +7

Delafossite compounds containing rare-earth ions have been proven to be an ideal platform to investigate frustrated magnetic ground states. Here, we discuss two triangular-lattice…

Magnetic anisotropy and dipolar interactions in the frustrated triangular-lattice magnet NaGdS_2

J. Grumbach, E. Häußler, S. Luther +12

In this comprehensive study, we present results of bulk measurements (magnetization, specific heat, ac susceptibility, thermal expansion, and magnetostriction) combined with local…

Spin Liquid Mimicry in the Hydroxide Double Perovskite CuSn(OH) Induced by Correlated Proton Disorder

Anton A. Kulbakov, Ellen Häußler, 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 Häußler +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…

Correlated proton disorder in the crystal structure of the double hydroxide perovskite CuSn(OH)

Anton A. Kulbakov, Ellen Häußler, 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…
