Dielectric permittivity and remanent polarization measurements have been performed in deuterated rubidium ammonium dihydrogen arsenate with x=0.28. Upon cooling the crystal, there is only the «transition» to the deuteron glass state. Static permittivity measurements were carried out along the a tetragonal axis at two different heating and cooling rates. Applying an external dc electric field along the a axis creates a bias which forces the acid deuteron in the O-D...O bond to lie at one end as opposed to the other as the temperature is lowered. This gives rise to a static permittivity (≃polarization and/or field) which freezes in below the glass «transition» temperature T g
