    Crystallographic features of the ferroelectric incommensurate phase in Pb(Zr1−xTix)O3 have been investigated by transmission electron microscopy, mainly using x = 0.05 samples obtained by cooling from a high-temperature paraelectric phase under an electric field of 500 V/cm. The present experimental data clearly indicate that the incommensurate and ferroelectric domains coexist independently, and that the incommensurate structure is characterized by not only a periodic-microdomain structure consisting of two M3 variants, but also a periodic array of antiphase boundaries for the M′5 antiferroelectric displacement. These observations suggest that the normal structure of the incommensurate structure should be ferroelectric and that the rotational angle of the M3 rotational displacement can be identified as a modulation mode. In addition, the antiphase boundary of the M′5 antiferroelectric displacement may play the role of discommensuration with a phase slip of Π.
