| Abstract: | The temperature autostabilizing nonlinear dielectric element (TANDEL) effect and second harmonic generation have been studied in the ferroelectric solid solutions of (Pb x -Ba1−x )TiO3 and (Pb x -Sr1−x )TiO3 near the Curie temperature used as TANDEL. The generated second harmonics are linear for low d.c. biasing fields with zero off-set while they decrease sharply at higher d.c. biasing fields. The results show that these solid solutions might be used as TANDEL elements. |
