Abstract
We present detailed temperature- and field-dependent data obtained from magnetization, resistivity, heat capacity, Hall resistivity and thermoelectric power measurements performed on single crystals of CeZn11. The compound orders antiferromagnetically at ∼2 K. The zero-field resistivity and thermoelectric power data show features characteristic of a Ce-based intermetallic with crystal-electric-field splitting and possible Kondo lattice effects. We constructed the T−H phase diagram for the magnetic field applied along the easy [110] direction, which shows that the magnetic field required to suppress TN below 0.4 K is in the range of 45–47.5 kOe. A linear behavior of the ρ(T) data, H∥ [110], was observed only for H=45 kOe for 0.46 K ≤T≤ 1.96 K followed by the Landau–Fermi-liquid regime for a limited range of fields 47.5 kOe ≤H≤ 60 kOe. From the analysis of our data, it appears that CeZn11 is a local moment compound with little or no electronic correlations arising from the Ce 4f shell. The thermoelectric and transport properties of CeZn11 are mostly governed by the crystal-electric-field effects. Given the very high quality of our single crystals, quantum oscillations are found for both CeZn11 and its nonmagnetic analog LaZn11.
