                      ferroelectric BaTiO3 matrix are an example for a two‐phase
                      magnetoelectrically coupled system. They operate at room
                      temperature and are free of any resource‐critical
                      rare‐earth element, which makes them interesting for
                      potential applications. Prior studies succeeded in showing
                      strain‐mediated coupling between the two subsystems. In
                      particular, the electric properties can be tuned by magnetic
                      fields and the magnetic properties by electric fields. Here
                      we take the analysis of the coupling to a new level
                      utilizing soft X-ray absorption spectroscopy and its
                      associated linear dichroism. We demonstrate that an
                      in‐plane magnetic field breaks the tetragonal symmetry of
                      the (1,3)‐type CoFe2O4/BaTiO3 structures and discuss it in
                      terms of off‐diagonal magnetostrictive‐piezoelectric
                      coupling. This coupling creates staggered in‐plane
                      components of the electric polarization, which are stable
                      even at magnetic remanence due to hysteretic behavior of
                      structural changes in the BaTiO3 matrix.},
