Temperature Dependence of Magnetization in Quasi-One-Dimensional Ising Spin System of (Remark: Graphics omitted.)

Abstract

Development of the magnetization with temperature towards its saturation value is investigated by proton NMR experiment in CoCl₂·2H₂O, [(CH₃)₃NH]CoCl₃·2H₂O and CoCl₂·2NC₅H₅, which are approximated to a ferromagnetic Ising chain of (Remark: Graphics omitted.). The magnetization saturates at closer temperature to the transition temperature, as the interchain interaction becomes weaker.
