Mn-doped AgInS2 crystals are grown by a hot-press method at 700 °C for 1 hour under high pressure of 25 MPa from stoichiometric Ag 2S and In2S3 powders with the Mn atoms with a concentration between 5 and 20 mol.%. Mn-doped crystals showed diffraction lines of orthorhombic AgInS2 and AgIn5S8 in addition to the dominant lines of chalcopyrite AgInS2. The S composition in the crystals is slightly deficient independent of the Mn concentration. Electron states of Mn are studied by an electron spin resonance (ESR) at room temperature. The ESR intensity of the Mn-doped crystals increases with an increase in the Mn concentration. The g-factors at room temperature of the Mn-doped crystals are in the range 1.980-1.982 with the peak-to-peak linewidth in the range 4.5-8.9 mT.
