The physical properties of the very-heavy-fermion compound YbCu4Ni were characterized through structural, magnetic, thermal, and transport studies along nearly four decades of temperature ranging between 50 mK and 300 K. At high temperature, the crystal electric field level splitting was determined with Δ1(Γ6)=85K and Δ2(Γ8)≈200K, the latter...

Among the new discovered intermetallics in the Yb-Pd-Sn system, the cubic phase Yb3Pd4Sn13, with a lattice parameter of 0.9743(5) nm, emerges as a new member of the R3T4Sn13 family (R = rare earth element, T = transition metal) crystallizing in the Yb3Rh4Sn13-structure type. The effective magnetic moment μeff = 1:84 μB/Yb is strongly reduced....

Phase equilibria in the Yb−Pd−Sn ternary system at 600 °C were established in the Pd ≤ 75 at.% concentration range employing X-ray diffraction (XRD), scanning electron microscopy (SEM) and electron probe micro-analysis (EPMA). Besides the known intermetallic compounds, three new ternary intermetallics were revealed in the system, together with...

We report on synthesis, crystal structure, magnetic, thermodynamic, and transport properties of the compound YbPd2In, crystallizing as a Heusler structure type. A trivalent state of the rare earth was determined by fitting the magnetic susceptibility with a Curie-Weiss law. This compound is characterized by showing very weak magnetic...

In the heavy-fermion system Yb2Pd2In1-xSnx, the interplay of crystal-field splitting, Kondo effect, and Ruderman-Kittel-Kasuya-Yosida interactions leads to complex chemical-, pressure-, and magnetic-field phase diagrams still to be explored in full detail. By using a series of techniques, we show that even modest changes of parameters other...
