✦ Synopsis

We have investigated the crystal and magnetic structure of Nd2CuO4 at millikelvin temperatures. No distortion of the tetragonal structure could be detected with the present instrumental resolution. The refinement of the crystal structure with the intensities of 88 independent nuclear reflections measured at 500 mK lead to an agreement factor R = 0.057. The magnetic structure was refined with 15 independent magnetic reflections measured at 80 mK which lead to an agreement factor of R = 0.136. The magnetic moments of Nd and Cu atoms were found to be 1.3( 1 ) and 0.47 (8)/ta, respectively, at T=80 mK. The magnetic moments of Nd and Cu atoms are parallel to the crystallographic [ l l 0 ] direction. No evidence for a component of moment parallel to [ 0 0 l ] could be obtained from the present investigations.
