The magnetodielectric (MD) effect in two-layer composites consisting of polarized PbZr 0.53 Ti 0.47 O 3 (PZT) ceramics and Mn 0.4 Zn 0.6 Fe 2 O 4 (MZF) ferrite plates has been studied. The MD coefficient ε/ε(0) was established to depend on a thickness of the magnetostriction layer, a bias magnetic field strength, and an electric field frequency. Using thermodynamic approach an inspection of obtained results for two-layer structure has been carried out.

The gluebond and its role in the EMC offect are proposed in this paper.The discrepancy between electro-and muon-production data can be ascribed to the QCD evolution of the gluebond in nuclei.The enhancement of the gluon distribution at small x, observed in J/iJ) muon-production experiment, can be also explained by using the gluebond model.

We introduce the coordinate-dependent two-mode squeezing transformations and discuss the properties of the corresponding two-mode squeezed states.
