N2 - In the last quarter of a century, neutron-scattering measurements have provided important clues for understanding the novel magnetism of carrier doped cuprate oxides. Discovery of evidence for charge-density-wave (CDW) and spin-density-wave (SDW) orders in La 1.6-xNd 0.4Sr xCuO 4 with x ∼ 1/8 has attracted much attention on the universality of inhomogeneous carrier distribution in CuO 2 planes, namely stripe correlations, and its relevance to the superconductivity. Here we review the nature of charge and spin stripe orders in a prototypical superconducting La-214 system, which has been investigated mainly by neutron scattering measurements. After introducing the hole concentration range, where the each order can be observed, characteristic features of low-energy spin fluctuations in the stripe ordered and disordered La 2-xBa xCuO 4 with x ∼ 1/8 will be discussed in terms of fluctuating stripes. The impact of magnetic field and impurity substitution on the orders is also presented, followed by a comparative study on electron-doped cuprates. Finally, we will give a brief summary of experimental trends.
