Ultralow-Frequency internal friction mechanisms in ferroelectrics

Influence of diffuse phase transition on the anelastic behavior of Nb-doped Pb(Zr0.53Ti0.47)O3 ceramics

“…It is well known that anelastic spectroscopy is very sensitive to the structure of the material, especially to the point defects [10][11][12][13][14], domain walls [13][14][15][16][17] and spurious phases [18]. Several studies, related to the oxygen vacancies, domain walls and phase transitions in ferroelectric ceramics, have employed M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT internal friction (Q −1 ) measurements [5,[10][11][12][17][18][19][20][21][22][23][24][25][26].…”

Absorption of 90° domain walls to oxygen vacancies investigated through internal friction technique

“…IF measurements are very sensitive to phase transition and micro-unit relaxation process, such as jumping of point defects, viscous motion of domain walls, interaction between points defects and domain walls and other imperfections (dislocations or domain walls), etc. [19][20][21]. Thus, they can detect those processes which other measurements cannot detect.…”

Mechanical loss associated with the grain size in lead zirconate titanate ceramics

“…However, the mechanism that the oxygen vacancies and domain walls play a decisive role in the applications of ferroelectrics, is still not very clear up to now. It is well known that the internal friction method is very sensitive to the microstructure of materials and thanks to it's analytical possibilities [1][2][3][4][5] can give true information about acoustic loss mechanisms and reconstruction of domain structure, domain boundary kinetics as well as permits to estimate different microstructure parameters.…”
