Ferroelectric phase transition in lead germanate Pb₅Ge₃O₁₁ studied by ESR of Gd³⁺ probe
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...

| description |
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 below TC. Anomalous line width broadening observed
around TC can be associated with a quasi-elastic central peak component
of excitation spectrum, observed earlier using a light scattering experiment
and attributed to static symmetry-breaking defects. |
