The abstract of the article is reproduced below: Frustrated magnetism in face-centered cubic (fcc) magnetic sublattices remains underexplored but holds considerable potential for exotic magnetic behavior. Here, we report on the crystal structural, magnetic and thermodynamic properties of the A-site-vacant double hydroxide perovskite MnSn(OH)₆. Despite dominant antiferromagnetic interactions among Mn²⁺ moments, evidenced by a negative Curie-Weiss temperature, the lack of a sharp thermodynamic transition down to 350 mK implies the absence of long-range magnetic order. However, a broad hump at 1.6 K suggests short-range correlations and spin freezing, with power-law behavior consistent with a spin-glass state. Neutron diffraction at low temperatures confirms the presence of three-dimensional (3D) antiferromagnetic correlations, manifesting as diffuse magnetic scattering with a correlation length ξ = 24.66 Å and a magnetic propagation vector k = (0 0 ½) at 20 mK.Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/3::32::307::307-013::31::322::322-01
