ESR spectra of Gd³⁺ probe have been studied in the range of ferroelectric phase transition TC=451 K in lead germanate Pb₅Ge₃O₁₁. Measurements of ESR line position have shown that local order parameter behaves in accordance with the mean field theory approach in a broad (∼150 K) temperature interval...
