摘要：

The Rhodes-Wohlfarth ratio mu(c)/mu(p), where mu(c) is the dipole moment determined from the Curie-Weiss constant and mu(p) the saturated dipole moment, was examined for LiTlC4H4O6.H2O (LTT), a displacive ferroelectric having a low Curie temperature of 10 K. The value of mu(c)/mu(p) of LTT is obtained to be about 18, which is much larger than those of other ferroelectrics examined previously. This result supports Tokunaga's prediction that mu(c)/mu(p) of displacive ferroelectrics with low Curie temperature exhibit large deviation from unity.
