摘要：

A series of polycrystalline Ca3Co2-xMnxO6 with 0.93 < x < 1.07 are prepared in order to investigate the effect of Co:Mn ratio around x similar to 1.0 on the multiferroicity. It is found that the ferroelectric polarization P at low temperature shows significant dependence on the Co:Mn ratio, forming a V-shaped pattern with the lowest point at x similar to 0.99. It is proposed that the suppression of P with the Co:Mn ratio approaching to the best Co/Mn order originates from the disruption of the long range spin order. (C) 2010 American Institute of Physics.
