Abstract

The absence of an anomaly in the linewidth temperature dependence of the Eu^{3+ 5}D₀→⁷F₁ emission lines near T_c is explained by the small contribution of the low q soft modes to the effective velocity of sound. The rapid migration model is used to calculate the Tb³⁺ (donor) - Eu³⁺ (acceptor) dipol-dipole interaction parameters in the 45-250K temperature range from the time decay curves of the ⁵D₄ manifold emissions of Tb³⁺.
