The electrical properties of ferroelectric substances are investigated and related to the Curie-Weiss law. A cryogenic experiment suitable for students measures the electrical susceptibility of strontium titanate in the 90-300 K temperature range. By measuring the electrical susceptibility of a modified barium titanate ceramic between 273 K and 343 K a phase transition is clearly observed at 304 K.
