Abstract
In this work, the hexagonal variant of the Ce2PdGe3 system is studied, which crystallizes in the AlB2-type structure (space group P6/mmm, hP3) and exhibits cluster spin-glass type behavior. The physical properties are studied by magnetization, heat capacity and electric resistivity, which showed that AlB2-type Ce2PdGe3 (h-Ce2PdGe3) can be classified as a cluster glass material with the freezing temperature Tf = 3.44 K in contrast to the behavior of the previously described tetragonal variant, which shows a double antiferromagnetic transition at TN1 = 11 K and TN2 = 2.3 K. The X-ray photoelectron spectroscopy measurements reveal that the Ce 4f states are well localized. In addition, the magnetocaloric effect in this compound is examined. The maximum values of magnetocaloric parameters appear in the vicinity of 7–9 K. For a magnetic field change of 50 kOe, the value of the change in magnetic entropy is 2.6(1) J kg−1 K−1 and the adiabatic temperature change is ≈8 K.
