Roles of the Higher Order Anisotropic Terms in Successive Structural Phase Transitions: The Method of Determination of Phenomenological Parameters
TL;DR: In this paper, a simple and general method for choosing appropriate coefficients of the higher order invariants in the free energy function to reproduce successive phase transitions is presented, when applied to perovskite structure-based systems.
Journal ArticleDOI
Domain Wall Structure in Pb(Zn1/3Nb2/3)O3-PbTiO3-Mixed Crystals by Atomic Force Microscopy
Makoto Iwata,Kohei Katsuraya,Shinichi Tachizaki,Jiri Hlinka,Ikuo Suzuki,Masaki Maeda,Naohiko Yasuda,Yoshihiro Ishibashi +7 more
TL;DR: In this paper, the authors showed that all of the ferroelastic domain wall structures observed in the tetragonal and rhombohedral phases can be explained by the Sapriel theory and concluded that no ferroelectric charged domain wall exists in the PZN-8%PT crystal without an external field.
Journal ArticleDOI
Pressure-induced dielectric change from relaxor to antiferroelectric behavior in disordered Pb(In1/2Nb1/2)O3
Naohiko Yasuda,Hidehiro Ohwa,Jun Oohashi,Kenji Nomura,Hikaru Terauchi,Makoto Iwata,Yoshihiro Ishibashi +6 more
TL;DR: In this paper, the dielectric properties of Pb(In 1/2 Nb 1 2 )O 3 (abbreviated as PIN) single crystal were investigated under hydrostatic pressures up to 0.7 GPa.
Journal ArticleDOI
Improper Ferroelectric Phase Transitions
TL;DR: In this article, the phase transition in ammonium Rochelle salt is discussed from the symmetry point of view and the role of identity representation in the theory of phase transitions is briefly discussed.
Journal ArticleDOI
Measurement of Dielectric Constant Near 170 K in (CH3NH3)5Bi2Cl11 Single Crystal
Makoto Iwata,Yoshihiro Ishibashi +1 more
TL;DR: In this article, temperature dependence of the dielectric constant in this temperature range has been explained applying the Landau theory, and no indication of any phase transition was obtained near 170 K.
