Abstract

Transient variations of the permittivity ϵ subsequent to applying or removing a d. c. electric field are measured in pure Rochelle salt before and after X‐ray irradiations with doses up to 5.82 × 10^6^ r. Irradiation is found to affect the form of the transient phenomena considerably. The maximum of the variations observed during the measurements shifts towards higher polarizing field strengths as irradiation dose increases. The variations diminish after sufficiently high irradiation doses.

It is proposed that the defects produced by irradiation at first only slow down the reorientational motion of the domains; however, as defects accumulate, they entirely immobilize an increasingly large proportion of the domains, thus preventing them from participating in the polarisation of the sample.
