Description

Structural phase transformations in (100)-oriented Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals have been investigated by X-ray diffraction. A cubic (C) → tetragonal (T) → monoclinic-C (MC) transformation sequence was observed in the field-cooled condition. Two phase coexistence regions of C + T and T + MC were found. In addition to an increase in the C → T phase transition temperature and a decrease of the T → MC one, a broadening of the coexistence regions was also found with increasing field. This broadening can be explained by the presence of polar nano regions within the C, T, and MC phase regions
