The Kondo Effect in Ce_xLaLuScY (x = 0.05-1.0) High-Entropy Alloys.

ABSTRACT: In the search for electronic phenomena in high-entropy alloys (HEAs) that go beyond the independent-electron description, we have synthesized a series of hexagonal rare earth (RE)-based HEAs: Ce_xLaLuScY (x = 0.05-1.0). The measurements of electrical resistivity, magnetic susceptibility and specific heat have shown that the Ce_xLaLuScY HEAs exhibit the Kondo effect, which is of a single impurity type in the entire range of employed Ce concentrations despite the alloys being classified as dense (concentrated) Kondo systems. A comparison to other known dense Kondo systems has revealed that the Kondo effect in the Ce_xLaLuScY HEAs behaves quite differently from the chemically ordered Kondo lattices but quite similar to the RE-containin
