Abstract
Precise dielectric-constant and hysteresis-loops measurements at very low heating and cooling rates (∼0.5°C/h) near Tc22.0°C in single crystals of triglycine selenate reveal previously unobserved discontinuities and a very small thermal hysteresis (ΔT0.05°C), indicative of a first-order transition very close to a tricritical point. The set of tricritical exponents β1/4, δ5, γ1, borne out by present data, and α1/2 (from Ema's specific-heat data) describe very well the observed behavior in the vicinity of the phase transition. © 1994 The American Physical Society.
