Abstract
The spontaneous electric polarization Ps has been measured for Gd2(MoO4)3 over the temperature range from 4.2 °K to the Curie point. Near 4 °K the maximum Ps is slightly less than 0.29 μC/cm2 with a very low temperature coefficient. An electric field enforced phase transition from paraelectric to ferroelectric at temperatures just above zero‐field Tc demonstrates the first‐order nature of the phase change. Better agreement was found near Tc between Ps and the relation (T − T1)1/3 than between Ps and a Landau‐type function.This publication has 7 references indexed in Scilit:
