Abstract
The complex permittivity of Triglycine Sulphate is measured from 0.5 to 4.5 kMc/s as a function of temperature. A dispersion is observed which is of a simple Debye relaxation rather than a resonance type. Thus the form of the relaxation differs from the Gaussian distribution of relaxation times found by HILL and ICHIKI. The relaxation frequency increases linearly with temperature above the Curie point. Above 0.5 kMc/s the real part of the permittivity undergoes a more and more pronounced minimum at the Curie point.
