Two-dimensional nano-flake of MoS₂ and Mo₀.₉₉₄Mn₀.₀₀₆S₂ were made by the hydrothermal method. X-ray diffraction, HRTEM images, EDS, and magnetic hysteresis study revealed the 0.6% Mn ions were doped. The varied-temperatures Raman spectra show the interlayer vibration mode was controlled by the magnetic field in the Mn-doped sample. The temperature profile of ac conductivity experiments shows a small peak at around 245 K for excitation frequencies between 20 and 2000000 Hz. It can be described by small polaron hopping mechanism. The activation energies above and below 245 K are 129 and 82 meV, respectively.
