The coexistence and coupling of ferromagnetic and ferroelectric orders in a single material is crucial for realizing next‐generation multifunctional applications. The coexistence of such orders is confirmed at room temperature in epitaxial thin films of BiFe 1− x Co x O 3 ( x ≤ 0.15), which manifests a spin structure change from a low‐temperature cycloidal one to a high‐temperature collinear one with canted ferromagnetism.
