| 中文摘要 | The spin ladder compounds Sr(14) Cu(24) O(41 + delta) were synthesized by conventional solid state reaction method with subsequent annealing at 400, 500, 600, 800 and 900 degrees C, respectively. The energy dispersive spectroscope ( EDS) measurement confirms that the content of oxygen in the samples decreases with the increasing of annealing temperature. The measurement of magnetic susceptibility reveals that the sample annealing at 600 degrees C has the largest number of dimers. The measurement of Raman spectrum shows some new Raman vibrational features. Corresponding to delta > 0 or delta < 0 in the sample, some Raman modes appear, and some other Raman modes disappear, which is due to the fact that the lattice distortion alpha = c(1)/c(c) is near the minimal value 10/7 and the Cu-O bond has relatively long length. |
