摘要：
Magnetic and magnetoresistance effect of needle shaped crystal and slightly Co rich Ca3Co2O6 was investigated in a temperature range between 2 and 100 K and in a dc magnetic field range less than 7 T and in pulsed fields less than 20 T. We found 1/3m(s) and 2/3m(s) plateaus of the magnetization for the full magnetization m, and large negative magnetoresistance effect of 10% at the same magnetic fields, respectively.
