Abstract
The behavior of the magnetic structure of the copper subsystem of Nd2C uO4 under the action of an external magnetic field has been studied. I t is shown that the spin-reorientation phase transition takes place wh en the external magnetic field is normal to the tetragonal crystal axi s. This transition is accompanied by unusual anomalies of elastic prop erties. The field dependence of the elastic moduli in the vicinity of the critical point is investigated.
