Influence of the low Mn intercalation on magnetic and electronic properties of 2H-TaS2 single crystals

Abstract The low-Mn-intercalated compounds 2H-Mn x TaS 2 ( x ≤0.1) single crystals were successfully grown via the iodine chemical vapor transport technique; the electrical and magnetic properties have been investigated systematically. No signs of charge density wave and superconductivity transitions appear down to 2 K even when x =0.02, while a small resistivity upturn has been observed in the low-temperature region for Mn x TaS 2 samples. A substantial magnetocrystalline anisotropy is observed and the Mn magnetic moments lie mainly parallel to the ab-plane. The glass behavior was observed in the low-temperature region firstly from the ac susceptibility measurement, the freezing of the glass may contribute to the upturn of the resistivity.
