摘要	The dc and ac magnetizations of the stripe-ordered La(1.6-x)Nd(0.4)Sr(x)CuO(4) (x=0.10,0.15,0.18) single crystals have been studied systematically under different magnetic-field orientations. It is found that the dc magnetizations M for all the three different doped samples show two diamagnetic steps for H parallel to c, while there is only one for H parallel to ab. The real part M(') of the ac magnetization is similar to that of the dc one and the imaginary part M(') shows two peaks at the temperatures corresponding to the two steps of M('). For comparison, the dc magnetization of La(1.85)Sr(0.15)CuO(4) single crystal without static stripe phase has only one transition for H parallel to c. The results suggest that the anisotropic magnetic properties in La(1.6-x)Nd(0.4)Sr(x)CuO(4) are closely related to the decoupling between the CuO(2) planes by the static stripe order which causes a two-dimensional superconducting state in the system.
