The anomalously large dielectric aging in ferroelectric partially deuterated potassium dihydrogen phosphate is found to have multiple distinct mechanisms. Two components cause a decrease in dielectric response over a limited range of fields around the aging field. Substantial aging occurs on time scales of ∼1000 s after a field change, as expected for a hydrogen/deuterium diffusion mechanism. A slower component can give an almost complete loss of domain-wall dielectric response at the aging… 


Aging dynamics in ferroelectric deuterated potassium dihydrogen phosphate
Anomalously large dielectric aging is found in the high-susceptibility plateau ferroelectric regime of ~95% deuterated potassium dihydrogen phosphate (DKDP). Much less aging is found in
Manifestation of a structural disorder in the polarization kinetics of a KD2PO4 ferroelectric
Crystalline potassium dideuterophosphate subjected to a slowly varying or a dc electric field has been found to exhibit polarization features which indicate the presence of a structural disorder
Aging, rejuvenation and memory due to domain-wall contributions in RbH2PO4 single crystals
Isothermal aging is studied for RbH2PO4 crystals which were slowly cooled below the ferroelectric phase-transition temperature Tc. Aging is strong within the temperature range Tc > T > Tf of high
Domain freezing in potassium dihydrogen phosphate, triglycine sulfate, and CuAlZnNi
The temperature dependence of the dielectric constant and dissipation in potassium dihydrogen phosphate (KDP), its deuterated compound (DKDP), triglycine sulfate (TGS), and TGS doped with
Effect of deuteration on the ferroelectric transition temperature and the distribution coefficient of deuterium in K(H1−xDx)2PO4
The variation in the ferroelectric transition temperature with deuteration is described by a linear function only if the deuteration level in the crystal is considered. A least‐squares fit of these
The influence of an electric field on the latent heat of the ferroelectric phase transition in KDP
The specific heat, heat flux (DTA trace) and dielectric constant of KDP ferroelectric crystal have been measured simultaneously for various electric fields with a conduction calorimeter. The specific
Aging, Thermal Hysteresis and Domain-Freezing in KH 2 PO 4
The isothermal decay of the permittivity of a KH 2 PO 4 crystal is investigated for various temperatures of the ferroelectric phase. The results show that both the strength and the velocity of the
Aging phenomena in spin-glass and ferromagnetic phases: Domain growth and wall dynamics
We compare aging in a disordered ferromagnet and in a spin-glass, by studying the different phases of a re-entrant system. We have measured the relaxation of the low-frequency ac susceptibility χ, in
Hydrogen–deuterium exchange in KD2PO4
Depth profiles of 1H and 2D in rapidly grown KD2xH2(1−x)PO4 single crystals are studied by elastic recoil detection analysis. Results show that, under ambient conditions, deuteration in the first
Domain wall freezing in KDP-type ferroelectrics
Abstract Hysteresis loops in KH 2 PO 4 (KDP) and its ferroelectric (FE) isomorphs disappear some 60 K below T c . This disappearance may result from an order–disorder transition of the domain wall.
