      abstract     = {An effective Hamiltonian scheme is used to reveal the
                      properties of a multidomain structure in BiFeO3 consisting
                      of alternating domains that are initially made of two
                      phases, namely, R3c (ferroelectric with antiphase oxygen
                      octahedral tilting) versus Pnma (antiferroelectric with
                      in-phase and antiphase oxygen octahedral tiltings). These
                      two types of domains dramatically modify their properties as
                      a result of their cohabitation. The weak ferromagnetic
                      vector and polarization rotate, and significantly change
                      their magnitude, in the R3c-like region, while the Pnma-like
                      region becomes polar along the direction of domain
                      propagation. Moreover, the domain walls possess distinct
                      polar and oxygen octahedral tilting patterns that facilitate
                      the transition between these two regions. The studied
                      multidomain is also predicted to exhibit other anomalous
                      properties, such as its strain adopting several plateaus and
                      steps when increasing the magnitude of an applied electric
                      field.},
