Abstract

The discovery of magnetism-driven ferroelectricity has recently given new hope for multiferroic devices, but very low magnetic ordering temperature as well as negligibly small electric polarization in these systems are still a challenge. Here, we report a new collinear magnetic multiferroic, Nd2CoMnO6 (T-C similar to 150 K) with a spontaneous electric polarization, P-S similar or equal to 1.3 mu C cm(-2), much higher than the other known magnetic multiferroics. The high polarization value has been associated to the intrinsic up arrow up arrow down arrow down arrow spin ordering-driven broken symmetry and the high degree of antisite disorder present in the system, which are confirmed through dc magnetization measurements.
