Abstract
Dielectric and magnetic resonance measurements have been carried out on NaNH4SeO4 · 2H2O and NaNH4SO4 · 2H2O. A dielectric anomaly as well as hysteresis loops were found. The dielectric anomaly occurred at 180°K in NaNH2SeO4 · 2H2O below which the P3 and Ec were measured as a function of temperature. PMR measurements were carried out on polycrystalline materials. The ferroelectric properties and the role of the NH, groups are discussed in light of the experimental resultsKeywords
