Ferroelectricity: Measurement of the dielectric susceptibility of strontium titanate at low temperatures

Matthew Trainer
2001 American Journal of Physics  
A cryogenic experiment determining the dielectric susceptibility of the ferroelectric substance, strontium titanate, in the 90-to 300-K temperature range is described. Evidence is presented for a structural phase transition in strontium titanate at 110 K. The experiment is suitable for advanced students.
