title: Study of the invar effect through ultrasonic measurements of the elastic properties of Fe(64)Ni(36) under pressure.
abstract: The elastic properties of a polycrystalline sample of invar Fe(64)Ni(36) have been investigated at ambient temperature by ultrasonic experiments up to 7 GPa. The pressure dependence of the bulk modulus is extracted without using any model and discussed in terms of invar anomaly models.
