Abstract

Permittivity versus temperature characteristics and Curie-Weiss exponent (CWE) γ in the universal Curie-Weiss law [ε-1 = εm -1 [1+ (T- Tc) γ (2 δ2)] (1≤γ≤2)] as a function of dc bias field were obtained for 〈001〉, 〈011〉, and 〈111〉 oriented 0.76Pb (Mg13 Nb23) O3 -0.24PbTi O3 single crystals. Results indicated that γ is a function of dc bias field and three different oriented crystals show slight different γ values but the similar dc field dependence.
