摘要：

X-ray and neutron diffraction have been used to study the magnetic and structural properties of single crystal Nd2CuO4. We previously observed a small distortion of the basic tetragonal structure, whereby peaks such as ( 1 2 1 23) were observed with both X-ray and neutron diffraction. We explicitly show that these are not due to λ/2 wavelength contamination, as recently suggested. We also clarify the nature of the magnetic structures observed in this material. In particular, with the present neutron diffraction data on multidomain samples, it is not possible to distinguish between the collinear and noncollinear spin configurations which have been proposed for this system. © 1990.
