X-band EPR spectra of PLZT 1/65/35 and PLZT 8/65/35 doped with 1% Fe3 were recorded temperature range -175 degrees C to 200 degrees C. Thre
e types paramagnetic centers were found. Two of them are In strong axi
al and rhombic crystal field due to neighboring oxygen and lead vacanc
ies. The other center has syrmmetry determined by polarization and oxy
gen octahedra tilt. EPR spectra of PLZT 9/65/35 are in agreement with
its glassy behavior.
