“…The isoelectronic and isostructural compounds ReX 3 (Re = rare earth; X = In, Ga, Tl, Sn, and Pb) that crystalize in a cubic Cu 3 Au structure with the space group Pm 3m (no. 221) have attracted much attention for their novel physical properties, including unconventional superconductivity [1,2], heavy fermion [3], valence fluctuation [4], non-Fermi-liquid behavior [5,6], antiferromagnetic (AFM) ordering [7], and so on. According to the previous neutron-diffraction studies, most of ReX 3 compounds are antiferromagnets [8].…”

The AuCu3-type intermetallic compounds ReIn3 (Re = a rare earth ion) with type-IV magnetic space groups are predicted to show topologically nontrivial electronic states. Here, we grow ErIn3 single crystals, and study their magnetic properties and critical behaviors by means of the magnetic susceptibility, and magnetization isotherm measurements. Combining a detailed analysis of the magnetic susceptibility and isothermal magnetization, we find that this compound harbors a complicated magnetic phase diagram, and its magnetic moment arrangement appears not to simply follow the fashion as observed in the isostructural counterpart GdIn3 (it adopts a conventional type-C magnetic structure that belongs to type-IV magnetic space groups). A careful study of the magnetic properties around the antiferromagnetic-paramagnetic transition yields the critical exponents β = 0.309 (0.297), γ = 1.117 (1.038), and δ = 4.617 (4.454), indicating that the tricritical mean field model or the 3D Ising model works for ErIn3's magnetic behaviors and the presence of a long-range antiferromagnetic interaction therein. Besides, the exchange interaction distance J(r) ~ r-4.665 as well confirms a long-range magnetic coupling in ErIn3. Our results offer the clues that the magnetic structure varies from one member of ReIn3 family to another, and to confirm their electronic features in the antiferromagnetic phases further experimental and theoretical studies are still desired.
