英文摘要The structure, magnetic and transport properties of quasi-one-dimensional spin chain compounds Ca3-xSmxCo2O6 (0 <= x <= 0.8) were investigated. It is found that the intra-chain magnetic exchange coupling constant J and Weiss temperature theta decrease considerably with increasing Sm-doping content x and the sign of J and theta changes from positive to negative as x reaches to 0.6. The result shows that the dominated intra-chain magnetic coupling can be changed from ferromagnetic (FM) to antiferromagnetic (AFM) by Sm-doping. Moreover, the magnetic ground state of Ca3Co2O6 is changed from the spin density wave (SDW) phase to AFM state in Sm-doped samples. The resistivity decreases sharply first with a small amount of Sm-doping and then increases slightly as x increases further, which is a result of the competing effect between carrier concentration variations and lattice distortion. The thermopower has a similar variation trend with that of resistivity. The increased carrier concentration and enhanced spin entropy may be the origin of the change of the thermopower.
