One-dimensional magnetism in synthetic Pauflerite, $\beta$-VOSO${}_4$

Abstract

We have synthesized single-crystal samples of $\beta$-VOSO${}_4$ and fully characterized their magnetic properties. Our magnetic susceptibility, high field magnetization and powder inelastic neutron scattering results are in excellent agreement with theoretical expressions for a one-dimensional spin-1/2 Heisenberg chain with an exchange parameter of $3.83(2)$ meV. Ab initio calculations identify the superexchange pathway, revealing that the spin-chain does not run along the expected crystallographic chain $a$ direction but instead between V${}^{4+}$O${}_6$ octahedra that are linked via SO${}_4$ tetrahedra along the $b$ axis. We do not detect any phase transition to a long-range magnetic order within our experimental conditions, indicating $\beta$-VOSO${}_4$ is very close to an ideal one-dimensional magnetic system.
