摘要：

Permittivity versus temperature characteristics and Curie-Weiss exponent (CWE) gamma in the universal Curie-Weiss law [epsilon(-1)=epsilon(-1)(m)[1+(T-T-c)(gamma)/(2 delta(2))](1 <=gamma <= 2)] as a function of dc bias field were obtained for < 001 >, < 011 >, and < 111 > oriented 0.76Pb(Mg1/3Nb2/3)O-3-0.24PbTiO(3) single crystals. Results indicated that gamma is a function of dc bias field and three different oriented crystals show slight different gamma values but the similar dc field dependence.
