Abstract
The field and temperature dependencies of the spin structures in the normal states ofLa1.6 − xNd0.4SrxCuO4 (x = 0.10, 0.12, and 0.15) single crystals have been studied by measuring the magnetoresistanceand susceptibility. A negative magnetoresistance appears just belowthe spin-ordering temperature for the magnetic fields parallel to theCuO2 plane, which can be attributed to the spin-flop transition of the special spin structure inthe normal state of the system. The anisotropic variations of susceptibilities withtemperature for all the three specimens can be described in the framework of thecrystal-field theory. The well fitted broad peaks of the in-plane susceptibilitiesχab for the specimens suggest that the susceptibilities are dominated byNd3 + , and thus the spinreorientation of Cu2 + in the CuO2 plane can not be observed from the study of the susceptibility.
