“…Most of these properties are directly related to the displace phase transition from the basic perovskite structure to a more complicated perovskite-derived structure. Domain and domain boundaries appear after the phase transition, a consequence of the lower symmetry [3,4]. Geometrically, the formation of the domains and domain boundaries can be related to the distortion of the basic ABO 3 perovskite unit [5][6][7][8][9].…”

“…Fk2 J2 = Fk3 J3, on doit avoir: k 1 + k 2 = k 3 + K, K 6tant un vecteur du r6seau r6ciproque. Ce cas peut se produire si Ge est un groupe orthorhombique de r6seau (Guymont, 1978): les domaines ont done le m~me groupe de sym6trie, mais les 61~ments de ce groupe peuvent varier en orientation et en position d'un domaine/l l'autre. Trois cas doivent &re distingu6s: (Dans les deux premiers cas, H e n'est pas maximal.)…”

“…Trois cas doivent &re distingu6s: (Dans les deux premiers cas, H e n'est pas maximal.) Ces transitions s'accompagnent d'un changement de syst6me cristallographique: on a des macles par pseudo-sym~trie (Friedel, 1964), alors que dans le cas des macles parfaites H et G appartiennent au m~me syst~me et H est un sous-groupe invariant de G. (maille 2a,2b,c) (Guymont, 1978): dans le premier cas seulement, H e est maximal. …”

“…1). This distortion is commonly encountered in perovskite-type materials, for example in: rare-earth aluminates [2][3][4], YAlO 3 [5], gallates [6][7][8], ferrites [9][10][11], titanates [12,13] under normal conditions and in some silicates at high pressures [14], causing ferroelastic properties as well as the appearance of antiphase boundaries [15,16]. The behavior of domains can strongly influence materials qualities, for example, the configuration of the magnetic domain structure in the solid state solution of rare-earth manganites [17].…”
