Piezoelectric softening in ferroelectrics: ferroelectric versus antiferroelectric PbZr${}_{1-x}$Ti${}_x$O${}_3$

F. Cordero, F. Craciun, F. Trequattrini +1

The traditional derivation of the elastic anomalies associated with ferroelectric (FE) phase transitions in the framework of the Landau theory is combined with the piezoelectric co…
