We report that CaMn(7)O(12) is a new magnetic multiferroic material. The appearance of a ferroelectric polarization coinciding with the magnetic phase transition (similar to 90 K) suggests the presence of ferroelectricity induced by magnetism, further confirmed by its strong magnetoelectric response. With respect to other known magnetic multiferroics, CaMn(7)O(12) displays attractive multiferroic properties, such as a high ferroelectric critical temperature and large polarization. More importantly, these results open a new avenue to search for magnetic multiferroics in the catalog of doped oxides.
