electrostriction

https://doi.org/10.1351/goldbook.ET07368
Contraction of a dielectric in an electric-field @G02669@.
Notes:
  1. For example, the contraction taking place around the charged centres created as a consequence of the sudden formation of separated positive and negative charges in the process of @E02011@.
  2. The thermodynamic description of electrostriction was given by Drude and Nernst in 1894 to explain the phenomenon of contraction of a continuum medium, such as an alkane, around charges suddenly produced in that medium.
