“…The sudden change of magnetoresistance at the switching field can be attributed to the domain reorientation parallel to the direction of the field [25], and the domain nucleation and domain wall propagation are the cause for the formation of the butterfly-shaped double-peak magnetoresistance [44]. When the magnetic field is 3T, the magnetoresistance is negative, and the negative magnetoresistance reaches a peak near the Curie temperature, which is mainly due to suppression of spin disorder resistivity with the magnetic field [45]. Figure 2E presents the Hall resistance of the FeTa 3 S 6 device measured at the selected temperature when the magnetic field is along the c-axis (for clarify, the data are equally spaced in the vertical direction).…”

Intercalated transition metal dichalcogenides have been widely used to study the magnetic and magnetoelectric transport properties in a strong anisotropic and spin–orbit coupling environments. In this study, ferromagnetic FeTa3S6 (also known as Fe1/3TaS2) single crystals were grown by using the chemical vapor transport method, and its magnetic and magnetoelectric transport properties were measured. The results show that FeTa3S6 has ferromagnetic ordered below 37K, with sharp switching of magnetization, butterfly-shaped double-peak magnetoresistance and anomalous Hall effect, and the magnetization and resistance have strong anisotropy. When a magnetic field is oriented parallel to the c-axis, the magnetoresistance exceeds 10% at a temperature of 10K, and negative magnetoresistance is generated when the magnetic field is larger than the switching field. When the direction of the magnetic field of 9T rotates from out-of-plane to in-plane, the anisotropic magnetoresistance exceeds 40%, and the angle-dependent Hall resistance presents a novel trend, which may be due to the existence of a topological Hall effect or other magnetic structures in the FeTa3S6 thin film. When the magnetic field of 9T rotates in the ab-plane of the sample, the in-plane anisotropic magnetoresistance conforms to the form of sin2φ. The experimental results of this study provide important information for the study of magnetic and magnetoelectric transport properties of intercalated transition metal dichalcogenides.

Intercalation of transition metal dichalcogenides with magnetic elements has been the subject of increasing research interest, aiming to explore novel magnetic materials with anisotropy and spin-orbit coupling. In this paper, two magnetic samples with varying Fe content have been prepared using different growth conditions via the chemical vapor transport method. A comprehensive investigation of the magnetic properties of the materials has been conducted using the Physical Property Measurement System (PPMS, EvercoolⅡ-9T, Quantum Design). The results reveal distinct features in the studied materials. Fe0.12TaSe2 exhibits significant ferromagnetism with a Curie transition temperature of 50 K. However, its in-plane magnetism is weak and no significant hysteresis loop is observed below the Curie temperature. On the other hand, Fe0.25TaSe2 exhibits antiferromagnetism without any hysteresis loop and has a Néel temperature up to 130 K. This finding is quite different from the intercalated iron in FexTaS2, where only an antiferromagnetic state occurs with x larger than 0.4. Our study thus provides updated insights into the magnetic properties of this new system and serves as a reference for future investigations of TaSe2 compounds with varying iron content.
