“…But the hump position of ac susceptibility χ ac ( T ) for H || ab at T = 28 K (Figure (f)) does not depend on the frequency of the ac field (inset of Figure (f)), in contrast to the typical behavior for spin glass state. Actually, besides the spin glass state, the long-range FM state with magnetic anisotropy (hard ferromagnet and sizable coercive field) and/or multidomain structure can also lead to this kind of irreversible behavior, , which has also been observed in other long-range FM single crystals, such as U 2 RhSi 3 . According to the approach proposed by Joy et al, the maximum of the ZFC χ( T ) curve and the irreversibility are related to the variation of the coercive field, which is a measure of the magnetic anisotropy.…”

We report structural properties, physical properties, and the electronic structure of van der Waals (vdW) crystal VI3. Detailed analysis reveals that VI3 exhibits a structural transition from monoclinic C2/m to rhombohedral R3̅ at T s ≈ 79 K, similar to CrX3 (X = Cl, Br, I). Below T s, a long-range ferromagnetic (FM) transition emerges at T c ≈ 50 K. The local moment of V in VI3 is close to the high-spin state V3+ ion (S = 1). Theoretical calculations suggest that VI3 may be a Mott insulator with a band gap of about 0.90 eV. In addition, VI3 has a relatively small interlayer binding energy and can be exfoliated easily down to a few layers experimentally. Therefore, VI3 is a candidate for two-dimensional FM semiconductors. It also provides a novel platform to explore 2D magnetism and vdW heterostructures in S = 1 system.

“…S 2 0 is the passive electrons reduction factor, f i (k, R i ) is the backscattering amplitude, λ is the photoelectron mean free path, δ i is the phase shift, and σ 2 i is the correlated Debye-Waller factor measuring the mean square relative displacement of the photoabsorber-backscatter pairs. The corrected Figure 3(a) shows the temperature dependence of mag- range FM single crystals, such as U 2 RhSi 3 [26]. The magnetization loops of FeCr 2 Te 4 for both field directions at T = 2 K confirms a large magnetic anisotropy and easy c axis [Fig.…”

We carried out a comprehensive study of magnetic critical behavior in single crystals of ternary chalcogenide FeCr2Te4 that undergoes a ferrimagnetic transition below Tc ∼ 123 K. Detailed critical behavior analysis and scaled magnetic entropy change indicate a second-order ferrimagentic transition. Critical exponents β = 0.30(1) with Tc = 122.4(5) K, γ = 1.22(1) with Tc = 122.8(1) K, and δ = 4.24(2) at Tc ∼ 123 K suggest that the spins approach three-dimensional Ising (β = 0.325, γ = 1.24, and δ = 4.82) model coupled with the attractive long-range interactions between spins that decay as J(r) ≈ r −4.88 . Our results suggest that the ferrimagnetism in FeCr2Te4 is due to itinerant ferromagnetism among the antiferromagnetically coupled Cr-Fe-Cr trimers.
