Ising-type behaviour of critical properties in weak ferroelectric Li₂Ge₇O₁₅
The dielectric constant ε and electron spin resonance spectra of Mn²⁺ ions have been studied in the range of the ferroelectric phase transition in Li₂Ge₇O₁₅ single crystals. Analysis of the experimental data permits one to estimate the critical exponents of dielectric susceptibility γ ≅ 1.25,...

| description |
The dielectric constant ε and electron spin resonance spectra of Mn²⁺
ions have been studied in the range of the ferroelectric phase transition in
Li₂Ge₇O₁₅ single crystals. Analysis of the experimental data permits one
to estimate the critical exponents of dielectric susceptibility γ ≅ 1.25, order parameter β ≅ 0.32 and correlation length ν ≅ 0.63. The values of the
critical exponents determined in a fairly broad temperature interval around
Tc, are consistent with the theoretical predictions of the Ising model with a
one-component non-polar ordering coordinate. |
