A study of temperature and composition dependence of the magnetic anisotropy in the tetragonal (HoxEr1−x)Fe10V2 polycrystalline compounds was made by means of the singular point detection technique. At 293 K the easy magnetization direction lies along the tetragonal c axis  in all the samples and the anisotropy field increases linearly with increasing Ho content. However, with decreasing temperature the competition among the anisotropy of the different magnetic sublattices gives rise to a spin reorientation transition axis to cone in Er containing samples. The TSR value increases with increasing Er content. A significant in‐plane anisotropy was found in all the compounds. This planar anisotropy is larger in HoFe10V2, where it favors the  direction of the basal plane, while in ErFe10V2 the  is the preferred direction. The difference between the anisotropy field along  and  directions was found to decrease with increasing Er content. A first‐order magnetization process of type 1 was observed below 120 K in all the compounds when the magnetic field is applied along the  direction.
