| 中文摘要 | We have measured the c-axis angular-dependent magnetoresistance (AMR) of a Na0.48CoO2 single crystal, with a magnetic field of 10 T rotating within Co-O planes. Below the metal-insulator transition temperature at 40 K, the AMR is dominated by a twofold oscillation due to the charge ordering. The fourfold and sixfold oscillations in AMR become pronounced below 25 K. The presence of this fourfold oscillation is consistent with the picture proposed by Choy (cond-mat/0502164) that the Co lattice will split into two orthogonal sublattices with one occupied by Co3+ ions and the other by Co4+ ions in low temperatures. Embedded in these orthogonal sublattices, a hexagonal lattice, formed by Co4+ spins, leads to the sixfold oscillation in AMR. |
