Anderson localization of electrons in high Fe-doped transition metal dichalcogenide 1T-Fe0.4Ta0.6Se2 single crystals
We report the synthesis of 1T-Fe0.4Ta0.6Se2 single crystal along with its magnetic and transport properties. Magnetic susceptibility and magnetization measurements reveal anisotropic behavior with no long-range magnetic order down to 1.8 K. Low-temperature transport measurements exhibit a three-dimensional variable-range hopping regime, indicative of the localization of electronic states at the Fermi level. These observations shed light on the complex physical properties of the 1T-TaX2 (X = S, Se) family, especially the electronic properties tuned by 3d element doping for potential applications.
