“…2,4,[12][13][14][15][16] Millman and Kirczenow 16 have shown that there are three kinds of Fe site in the FeCl 3 intercalate layers of stage-1 and stage-2 FeCl 3 GIC's. Their results for stage-2 FeCl 3 GIC are as follows.…”

“…The magnetic properties of FeCl 3 GIC's have been studied by many researchers for almost three decades. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] The pioneering work of the magnetic study on FeCl 3 GIC's was made by Karimov and co-workers. 1 They showed that the magnetic susceptibility of polycrystalline samples has a peak at 3.6 K for stage-1 GIC and at 7 K for stage-2 GIC, which is identified as the onset of antiferromagnetic and ferromagnetic phase transitions, respectively.…”

The magnetic phase transitions of stage-2 FeCl 3 graphite intercalation compound have been studied using superconducting quantum interference device dc and ac susceptibility measurements in the temperature range between 1.9 and 18 K. The temperature, frequency, and field dependence of aa Ј , aa Љ , cc Ј , and cc Љ clearlyshow that this compound undergoes two kinds of spin-glass phase transition at T SG (h) (Ϸ4.5-6.1 K) and T SG (l) (Ϸ2 -2.5 K), respectively. Both aa Љ and cc Љ have peaks at T SG (h) that shift to the low-temperature side with decreasing frequency. The spin-glass phase below T SG (h) may result from a competition between the antiferromagnetic XY -like Fe 3ϩ spins as the majority and the ferromagnetic Ising Fe 2ϩ spins as the minority. The absorption aa Љ has a peak at T SG (l) that shifts to the low-temperature side with decreasing frequency. No anomaly in cc Љ is observed at T SG (l) , indicating that only the XY components of spins contribute to this transition. The spin-glass transition below T SG (l) may result from a competition between the intraplanar nearest-neighbor antiferromagnetic and next-nearest-neighbor ferromagnetic intraplanar exchange interaction, which is responsible for a possible incommensurate in-plane spin structure at low temperatures. ͓S0163-1829͑98͒01725-1͔

Ferric chloride-graphite intercalation compounds (FeCl3 -GICs) with stage 1 and stage 2 structures were synthesized by reacting FeCl3 and expanded graphite (EG) in air in a stainless-steel autoclave. As rechargeable Li-ion batteries, these FeCl3 -GICs exhibit high capacity, excellent cycling stability, and superior rate capability, which could be attributed to their unique intercalation features. This work may enable new possibilities for the fabrication of Li-ion batteries.

“…However, Mössbauer spectroscopy reveals a more complex situation. Three distinct Fe sites (A, B, and C) are found in temperature-dependent Mössbauer measurements [16,17]. The majority component originates from site A and is attributed to Fe 3+ ions [16], the magnetic moments of which lie in the basal plane [16,17].…”

Magnetic phase diagram and cluster glasslike properties of stage-1 graphite-intercalated FeCl3

We present a comprehensive investigation of the magnetic properties of stage-1 graphite intercalated FeCl 3 using a combination of DC and AC magnetic susceptibility, thermoremanent magnetization, and field-dependent magnetization measurements. This van der Waals system, with a centrosymmetric honeycomb lattice, combines frustration and disorder, due to intercalation, and may be hosting topologically nontrivial magnetic phases. Our study identifies two magnetic phase transitions at T f 1 ≈ 4.2 K and at T f 2 ≈ 2.7 K. We find that the paramagnetic state, for T > T f 1 , is dominated by short-range ferromagnetic correlations. These build up well above T f 1 and lead to a significant change in magnetic entropy, which reaches S Pk M = −5.52 J kg −1 K −1 at 7 T. Between T f 1 and T f 2 , we observe slow spin dynamics characteristic of a cluster glasslike state, whereas for T < T f 2 , our results indicate the onset of a low-temperature long-range ordered state. The analysis of the experimental results leads to a complex phase diagram, which may serve as a reference for future investigations searching for topological nontrivial phases in this system.
