Inhaltsangabe:
- Orbital two-channel Kondo (2CK) effect is one of the crucial systems with non- Fermi liquid (NFL) behaviors. But the full three-regime transport evidence has never been observed in one sample. Here, all three-resistive regimes for the orbital 2CK effect induced by two-level systems (TLSs) have been observed in the van der Waals ferromagnet Fe3GaTe2. The electron behavior undergoes a continuous transition from electron scattering to the NFL behavior, and subsequently to Fermi liquid behavior. The magnetic field does not affect any regimes, indicating the non-magnetic origin of the TLSs in Fe3GaTe2. In addition, the slope of linear negative magnetoresistance, rather than the topological Hall effect, has been found to be related to spin-magnon scattering and can be used to infer the emergence of spin textures. Our findings indicate Fe3GaTe2 may be an ideal platform to study electron-correlation and topological phenomena.
