摘要: Abstract This work is dedicated to the research of dielectric parameters e 0 and tan δ electronic state regular doped ions in pure strontium titanate single crystals under T =10–300 K. An anomaly temperature dependence between 10 100 K was discovered for separate samples. The essential change spectroscopic transition some part Ti 4+ into 2+,3+ states has been studied detail.
