我们使用非弹性中子散射建立调制矢量δ和相关长度的无公度磁涨落在金属样品La 2-xSrxCuO 4（x = 0.075和0.14）。 在适合于正方形晶格的符号中，其中在未掺杂的情况下磁不稳定性发生在（pi，pi）处，矢量δ是沿着沿着（pi，0）和（0，pi）。 的相关长度zeta是大于载体之间的距离，是弱依赖于chi，和12和100 K之间的两种组合物显着变化。
We use inelastic neutron scattering to establish the modulation vectors-delta and correlation lengths for the incommensurate magnetic fluctuations in metallic samples of La2-xSrxCuO4 with x = 0.075 and 0.14. In notation appropriate for a square lattice where the magnetic instability in the undoped case occurs at (pi,pi), the vectors-delta are along (pi,0) and (0,pi). The correlation length-zeta is larger than the distance between carriers, is weakly dependent on chi, and changes significantly between 12 and 100 K for both compositions.
