Abstract: New single crystals of Li$_8$FeSm$_{22}$O$_{38}$ have been grown by spontaneous crystallization from a solution in melt. The structure of these crystals has been determined: it corresponds to the space group $Im\bar3m$. Investigations of the magnetic susceptibility in the ranges of temperatures 2–24 K and fields up to 50 kOe have revealed a magnetic transition near 3 K. The temperature behavior of the magnetic susceptibility of the two-level system has been simulated. The results of the simulation agree with the experimental data. The resonance properties of Li$_8$FeSm$_{22}$O$_{38}$ have been studied in the temperature range 100–300 K.
