We have performed measurements of temperature dependent electrical resistivity ρ ( T ) under pressures up to 27 kbar and down to 0.1 K on single crystals of the Ce3Ir4Sn13 heavy fermion compound. At ambient pressure (P=0) we have identified in the ρ ( T ) data interesting features associated with the presence of crystalline field effects, magnetic correlations, Kondo single impurity scattering and, possibly, a low temperature structural phase transition. All these features were mapped as a function of pressure which allowed us to construct a pressure–temperature phase diagram with these temperature scales. We have also carried out measurements of ρ ( T ) as a function of magnetic fields up to H=8 T and the important temperature scales in ρ ( T ) were followed with field. Enlightened also by temperature dependent specific heat experiments we discuss the possible microscopic origins of the features found in our ρ ( T ) data. |
