On the theory of dielectric spectroscopy of protein solutions [PDF]

Journal of Physics: Condensed Matter, 2012
We present a theory of the dielectric response of a solution containing large solutes, of a nanometer size, in a molecular solvent. It combines the molecular dipole moment of the solute with the polarization of a large subensemble of solvent molecules at the solute-solvent interface.

Electromagnon in ferrimagnetic eps-Fe2O3 nanograin ceramics

, 2013
Electromagnons are known from multiferroics as spin waves excited by the electric component of electromagnetic radiation. We report the discovery of an excitation in the far-infrared spectra of eps-Fe2O3 which we attribute to an electromagnon appearing ...

Dielectric Spectroscopy: Yesterday, Today and Tomorrow

Applied Sciences
The theory of orientational polarization and dielectric relaxation was developed by P. Debye more than 100 years ago. It approximates a molecule by a sphere having one or more dipole moments.
