In this contribution we present the results of direct measurements of the compressibility, in a wide temperature range, and studies of the linear thermal expansion under hydrostatic pressure using a modified strain gauge method in Ce3(FeTi)29. A large magnetic contribution (κm=0.13 Mbar−1) to the isothermal compressibility was observed in the ferromagnetic state in comparison with the compressibility in the paramagnetic state induced by pressure at room temperature. The pronounced lambda-shaped anomalies in the thermal expansion coefficient (negative values of α) and in the compressibility of the Ce3(FeTi)29 compound were simultaneously observed in the vicinity of TC. © 1996 American Institute of Physics.
