Abstract
The third and fourth order phonon anharmonic interactions external electric
field terms are added in the two-sublattice pseudospin model for PbHPO4 crystal. By
using double time thermal Green's function method modified model, theoretical
expressions for soft mode frequency, dielectric constant, shift, width and tangent loss
are evaluated for PbHPO4 crystal. Temperature and field variations of soft mode frequency,
dielectric constant and loss tangent are calculated numerically. Present theoretical results
agree with experimental result of Smutney and Fousek for dielectric constant of PbHPO4.
