摘要：

The low-frequency c-axis dielectric constant of La2CuO4+x exhibits values approximately 1500 for T less-than-or-equal-to 350 K with an added approximately 2000 enhancement in the vicinity of the magnetic ordering temperature. The possibility of a simultaneous (anti)ferroelectric-antiferromagnetic transition at 270 K is suggested, but experimental confirmation of the ferroelectric state is precluded by the high and field-dependent electrical conductivity.
