  Materials systems with spin chirality can provide ultra-high-density,
ultra-fast, and ultralow-power information carriers for digital transformation.
These material systems include magnetic skyrmions, chiral domain walls, spin
reorientation,and so on. The topological Hall effect (THE) has been identified
as the most convenient and effective tool for detecting the presence of spin
chirality in these systems. The research on the THE that may arise from spin
reorientation and specifically in Fe3Ge with spin reorientation remains an
unexplored area, so we study the THE in Fe3Ge Conduct systematic research.
X-Ray Diffraction (XRD) results indicate that our Fe3Ge ribbon sample has a
D019 structure. First-principles calculations and magnetic and electrical
testing confirm spin reorientation in the Fe3Ge ribbon sample at 350 K.The Hall
resistivity test results are consistent with our expectations, indicating the
presence of the THE in the Fe3Ge ribbon sample. The topological Hall
resistivity reaches a maximum value of 0.69 m{\Omega} cm at 400 K. For the
first time, a detailed experimental study of the THE in Fe3Ge with spin
reorientation has been conducted, introducing a new member to the family of
THE.
