Yet, the microscopic mechanism underlying the emergence of its versatile multiple-${\\mathbf Q}$ phases remains unresolved. Here, we elucidate the field-orientation dependence of the magnetic phase diagram and establish an effective spin Hamiltonian for SrFeO$_{3}$ that incorporates a cubic single-ion anisotropy together with bilinear and biquadratic interactions in momentum space.
