We report magnetic properties of a 4f honeycomb iodide SmI3 made up of edge-shared network of SmI6 octahedra. High temperature magnetic susceptibility indicates a G7 Kramers doublet ground state of Sm3+(4f5) ions stabilized by the spin-orbit coupling and octahedral crystal electric field, which interact with a Sm-I-Sm bond angle of nearly 90°. Magnetization measurements down to 0.1 K detected antiferromagnetic correlations and an anomaly in the magnetization curve before saturation without a sign of long-range order. Relevance between SmI3 and the antiferromagnetic Kitaev material proposed in the 4f-electron system is discussed.
