Abstract

Abstract Single crystal ac magnetic susceptibility and magnetization measurements of the linear chain RbMnF 4⋯H 2O are reported. A broad maximum around 42 K in the susceptibility fits to a Heisenberg S = 2 linear chain with | J|/ k = 6.2 K and g = 2.03. At 7.3 K a sharp peak in X′ d (alternating field parallel to the chains) accompanied by large X″ d signals indicates weak ferromagnetic behaviour. Magnetization measurements leads to a canting angle of ∼ 1.5°.
