Abstract

EPR studies of Mn2+ in ferroelectric lithium ammonium tartarate monohydrate (LAT) show that there are four Mn2+ complexes, which group themselves into two chemically different sets each containing two physically related sites at room temperature. It is inferred that Mn2+ enters into NH4+ site. The hyperfine separation of the central group ( ½ →-½) is found to be constant, which is not observed usually. It is suggested that the space group of LAT below Tc is P21.
