Abstract
The elastic constants of Nd3Se4 show an anomalous behaviour above and below Tc = 52 K. Band effects are assumed to be the origin of the softening of C' in the paramagnetic region. Below Tc extra shifts arise from magneto-elastic coupling. An elastic hysteresis is observed which is directly related to the magnetic hysteresis loop.
