摘要：

The multiferroic properties of HoMn2O5 have been extensively studied to gain understanding of the magneto-dielectric coupling in this compound. In this work, dielectric measurements as well as polarization measurements in isotropic pressure up to 18 kbar are presented. The results indicate that the pressure is able to induce the ferroelectric order at low temperature in multiferroic HoMn2O5 implying the stabilization of the commensurate magnetic structure. The observation reveals that the ferroelectricity and magneto-elastic properties are highly correlated in this system. (c) D 2006 Elsevier B.V. All rights reserved.
