“…Nevertheless, the critical exponent b ¼ 0.25(1) has been obtained in Ref. [19] in agreement with the XY chiral scenario [5], although, according to Ref. [18], b ¼ 0.358(15) is close to a non-chiral XY model.…”

“…Both have their own associated fascinating ground state physics, but still consist of stronger Heisenberg ferromagnetic correlations in 1D with weaker antiferromagnetic exchange between the ferromagnetic chains. [33,34] An interesting result in 1D magnetism can be found in the compounds Sr 3 CuIrO 6 and Sr 3 CuPtO 6 , which are 1D Heisenberg ferromagnetic and antiferromagnetic, respectively. Mixing of the two materials results in a random ferro/antiferromagnetic paramagnetic state, described as a quantum spin chain paramagnet.…”

Magnetic materials with strong local interactions but lacking long-range order have long been a curiosity of physicists. Probing their magnetic interactions is crucial for understanding the unique properties they can exhibit. Metal-organic frameworks have recently gathered more attention as they can produce more exotic structures, allowing for controlled design of magnetic properties not found in conventional metal-oxide materials. Historically, magnetic diffuse scattering in such materials has been overlooked but has attracted greater attention recently, with advances in techniques. In this study, we investigate the magnetic structure of metal-organic formate frameworks, using heat capacity, magnetic susceptibility and neutron diffraction. In Tb(DCO 2 ) 3 , we observe emergent magnetic order at temperatures below 1.2 K, consisting of two k -vectors. Ho(DCO 2 ) 3 shows diffuse scattering above 1.6 K, consistent with ferromagnetic chains packed in a frustrated antiferromagnetic triangular lattice, also observed in Tb(DCO 2 ) 3 above 1.2 K. The other lanthanides show no short- or long-range order down to 1.6 K. The results suggest an Ising-like one-dimensional magnetic order associated with frustration is responsible for the magnetocaloric properties, of some members in this family, improving at higher temperatures. This article is part of the theme issue ‘Mineralomimesis: natural and synthetic frameworks in science and technology’.

“…Introducing a "squash" mapping, we show that the magnetic properties of coupled spin chains can be phenomenologically described by a single-layer TLAF model with effective spinS. The crucial experimental step is a series of precise magnetic measurements conducted under high pressure up to P = 1.21 GPa on a CsCuCl 3 single crystal [35][36][37][38][39][40][41] , which allows us to determine the exchange couplings to great accuracy and, consequently, extract the parameters of the effective model. We thus demonstrate that the value of effective spinS can be actually controlled by external pressure through the change in the material parameters.…”

Continuous control of classical-quantum crossover by external high pressure in the coupled chain compound CsCuCl3

In solid materials, the parameters relevant to quantum effects, such as the spin quantum number, are basically determined and fixed at the chemical synthesis, which makes it challenging to control the amount of quantum correlations. We propose and demonstrate a method for active control of the classical-quantum crossover in magnetic insulators by applying external pressure. As a concrete example, we perform high-field, high-pressure measurements on CsCuCl3, which has the structure of weakly-coupled spin chains. The magnetization process experiences a continuous evolution from the semi-classical realm to the highly-quantum regime with increasing pressure. Based on the idea of "squashing” the spin chains onto a plane, we characterize the change in the quantum correlations by the change in the value of the local spin quantum number of an effective two-dimensional model. This opens a way to access the tunable classical-quantum crossover of two-dimensional spin systems by using alternative systems of coupled-chain compounds.
