✦ Synopsis
Polycrystalline NH4C10s and NDICIOI samples have anomalously increased dielectric permittivity below 240 K which depends on measuring voltage, on sample grain size and thermal history. Any sudden change in temperature or bias field provokes an immediate increase in permittivity followed by a slow decrease. The behaviour has analogies with a dipole glass, an incommensurate phase, spin glasses and ferromagnetic powders
