An investigation is made of the EPR spectrum of Cu 2+ ions in ferroelectric triglycine fluoroberyllate. The values g∥ = 2.24 g∥ = 2.06, and A = 132 cm −1 are similar to those obtained for copper ions in triglycine sulphate and diglycine nitrate. The new lines are typical of S = 1 and the spectrum is found to have an anomaly at the Curie point. The D parameter of the spectrum is linearly dependent on the spontaneous polarization changes.
