- Opis:
- Relaxor ferroelectrics $0.2PbSc_{1//2}Nb_{1//2}O_3-0.4PbMg_{1//3}Nb_{2//3}O_3-0.4PbZn_{1//3}Nb_{2//3}O_3$ ceramics were studied by means of the Fourier transform infrared reflection and THz transmission spectroscopy in the temperature range of 20-500 K. On heating from low temperatures, the $A_1$ component of the strongly split $TO_1$ mode softens towards the Burns temperature, but the softening ceases near 400 K, which could be a signature of polar cluster percolation temperature.
