N2 - We have investigated the structural, magnetic, and ferroelectric properties of Mn-substituted CuFeO2, i.e., CuFe1-xMn xO2 (0≤x≤0.2). CuFeO2 is a typical frustrated triangular lattice antiferromagnet due to its Fe3+ triangular configuration. Although the lattice constants and atomic bond distances do not change in the range of 0≤x≤0.2, structural modulation introduced by the Mn substitution affects the magnetic and dielectric properties. A multiferroic phase, where the antiferromagnetism and ferroelectricity coexist, is found in a narrow range of 0.01≤x≤0.1. The origin of the multiferroic characteristics is discussed in terms of the partial release of the spin frustration.
