It undergoes a metal-insulator transition at about  T  M−I  ∼ 8  K . This insulating state can be suppressed and a metallic or highly-conducting state can be restored by applying external magnetic field higher than 10 T. The nature of this phase transition and the ground state, whether a spin-Peierls or antiferromagnet, has not been clarified.  In this paper, we report the anisotropy of magnetic properties of λ-(BETS) 2 FeCl 4  studied using SQUID magnetometer. The temperature dependence of the static magnetic susceptibility below  T  M−I  was found to show a strong field dependence when the field is applied parallel to the crystalline long axis (H//c). The nonlinear behavior in magnetization (M-H), reminiscent of a spin-flop transition of antiferromagnet, is observed at magnetic fields around 1 T, well below the field necessary for restoration of highly-conducting state. This strong field dependence is absent for other magnetic field directions, suggesting that the ground state of λ-(BETS) 2 FeCl 4  is antiferromagnet rather than spin-Peierls."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004966542881923","@type":"Researcher","foaf:name":[{"@value":"M.
