Abstract

Acoustic properties anomalies near the points of phase transition in the magnetic subsystem of Nd 2 CuO 4 have been studied. A spontaneous ferroelastic phase transition at T = 5 K and magnetic field induced ferroelastic phase transition (PT) associated with continuous spin reorientations at T < 0.5 K have been found. The exchange nature of magnetoelastic coupling is suggested.
