Abstract

The structure of (DMET)₂FeCl₄ is featured with an alternate stacking of quasi-1D chain-based donor sheets and magnetic Fe ³⁺ (S=5/2) sheets. At ambient pressure, the salt shows metallic behavior down to ∼100K with the presence of a resistivity anomaly around 7K, at which the susceptibility has a broad maximum of magnetic short-range ordering in the Fe³⁺ magnetic sheet of d-electrons. An antiferromagnetic transition takes place at T_N=2.8K. The large Weiss temperature Θ = -1IK and the field dependent anomalies in the magnetoresistance, which indicate the presence of a strong antiferromagnetic interaction, suggest that the donor π-electrons mediate the interlayer interaction between the Fe³⁺ magnetic layers.
