| 英文摘要 | Hexagonal YMnO3 is an attractive multiferroic material whose polarization and magnetic orders are strongly coupled with each other. Doping different cations in hexagonal YMnO3 would influence its properties, especially the magnetic transition temperature (the Ne ' el temperature). In this work, by using first-principles calculations, we not only studied the effects of doping Fe and Cr ions at the Mn-site on the Ne ' el temperature, but also revealed that the variations of electronic structures and the extents of orbital coupling overlaps are both factors to determine the magnetic interaction strength and Ne ' el temperature for YMn1-x(Fe,Cr)xO3 (0 <= x < 0.3). Besides the Mn-site, doping rare earth element (La) at the non-magnetic Y-site also influences the Ne ' el temperature. These results are important to provide more understanding about the performance of multiferroic materials. |
