      abstract     = {Doping is a widely used method to tune the physical
                      properties of ferroelectric perovskites. Since doping can
                      induce effective charges, it is important to understand how
                      charges affect the chemical and physical properties of the
                      doped perovskites. Here, we propose two charge compensation
                      models, by adding the charge‐dipole interaction to the
                      effective Hamiltonian, which has not been done previously,
                      and numerically investigate how lanthanum doping affects the
                      ferroelectric phase transition temperature and the
                      hysteresis loop in BaTiO3. The consequences of the charge
                      compensation models are compared and discussed, revealing
                      that the electron compensation mechanism with some Ti4+ ions
                      changing to Ti3+ is critical to understanding the
                      donor‐doped perovskites.},
