Chemical Vapor Growth and Manganese Metal Intercalation of TiS2

TiS 2 crystals with a 1T-CdI 2 type layered structure have been grown by a chemical vapor reaction under different conditions of transport gas, size of ampoule, and temperature. Various attempts to intercalate Mn metals into the TiS 2 layers were made using electrochemical, dipping in pyridine solution, thermal diffusion, and direct reaction methods. The EPR signals of the Mn-intercalated TiS 2 show a Mn 2+ state with the g -value≈2 and the hyperfine structure constant. A =80 ×10 -4 cm -1 , indicating a strong ionic nature of the crystalline environment. A lattice expansion along the c -axis upon intercalation is discussed.
