| contents | In this work, we reveal the coexistence and correlation of a topological cusp anomaly in the planar Hall signal and a spin-flip scattering dominated positive longitudinal magnetoresistance (MR) across the entire temperature range below the Curie point in Fe3GeTe2. This correlation dies out exponentially as the magnetic field is directed away from the ab-plane, resulting in unusually sharp polar angle dependence of longitudinal MR and the Hall response. |
