Abstract

The phase transitions in squaric acid, a two-dimensional antiferroelectric system, was observed by using 1H nuclear magnetic resonance. The spin-lattice relaxation time was measured using the inversion recovery method, and spin-spin relaxation time was obtained from solid echo decay. To check the possibilty of decomposition of the sample by heating, differential scanning calorimetry (DSC) measurements were employed, which indicated no changes upon thermal cycling. The spin relaxation measurements indicated a slow-motion limit.
