 Abstract: Herein, we present an extensive study of the magnetic and magnetotransport properties of iron-inserted transition-metal dichalcogenide Fe1/3TaS2. High-quality single crystals were prepared by an improved protocol for chemical vapor transport. The crystals show a sharp ferromagnetic order transition at the Curie temperature TC = 38 K, a very high anisotropy field of 79 T, and slow relaxation of the magnetization below TC. The field-dependent Hall resistivity in the ferromagnetic regime does not follow the M(H) curves, which could be explained by the unusual large negative magnetoresistance that reaches values of up to -72 under a field of 9 T. The large temperature and field dependence of the Hall effect and magnetoresistance near the Curie temperature point to a strong interaction of the charge carriers with thermally induced fluctuations of the spins. ©
