Multiferroic properties of HoMn2O5 compounds: A Monte Carlo Study — •A.S ERCHIDI ELYACOUBI, R Masrour, and A Jabar — Cady Ayyed University, National School of Applied Sciences, PB 63 46000, Safi, Morocco.

The class of HoMn2O5 compounds offers multiferroic properties where the refined magnetic zig-zag order breaks the inversion symmetry. The polarization and magnetization are found. The ferroelectric transition temperature are determined. The polarization is induced solely by different exchange couplings of the two different Mn4+ and Mn3+ magnetic ions. The magnetic and ferroelectric cycle have been deduced. The variation of the polarization by an external magnetic field depends strongly on the direction of that field. HoMn2O5 compounds;
