  • Abstract

    By fitting model values of physical quantities for deuterated TGSe crystal in theoretically derived expressions for ferroelectric mode frequency, dielectric constant and loss tangent in our earlier paper temperature dependences of these quantities have been calculated. Present results agree with experimental data of literature value.
