摘要We report a systematic study of the structure, electric, and magnetic properties of Ca3Co2-xMnxO6 single crystals with x = 0.72 and 0.26. The dc and ac magnetic susceptibilities display anomalies with characteristic of the spin freezing. The crystals show ferroelectric transition at 40 and 35 K (T-FE) for x = 0.72 and 0.26, respectively, with a large value of 1400 mu C/m(2) at 8 K for the electric polarization (P-c) along the spin-chain (c-axis) direction. Interestingly, the electric polarization perpendicular to the chain direction (P-ab) can also be detected and has the value of 450 and 500 mu C/m(2) at 8 K for the x = 0.72 and 0.26 samples, respectively. The specific heat and magnetic susceptibility show no anomaly around T-FE, which means that the electric polarization of these samples has no direct relationship with the magnetism. The x-ray diffraction and the Raman spectroscopy indicate that these samples may undergo Jahn-Teller distortions that could be the reason of electric polarization.
