摘要

The electron spin resonance (ESR) of the NH3+ free radical has been used to investigate the ferroelectric to the antiferroelectric transition in LiNH4SO4 crystals. A sharp transition at 286 K was detected by ESR in the form of line-splitting. The NH3+ free radical in the ferroelectric phase splits into two inequivalent species with different reorientational characteristics below the transition temperature. Twinning was simultaneously detected at the transition.
