抄録
We present a detailed study of the physical properties of single crystalline UPt2Si2. By neutron diffraction we establish the presence of frozen-in strain disorder on the Pt(2)/Si(2) ligand sites within the tetragonal crystal structure. Further, the system undergoes an antiferromagnetic transition at TN=32 K. In the range TN<T<Tirr\\simeq36 K we observe a cluster glass like phase as result of the disorder. The highly anomalous behavior of the electronic transport properties—metallic along the tetragonal a and localized along the c axis—is a result of the specific type of disorder. Altogether, UPt2Si2 emerges as a model compound to study disorder effects in f electron intermetallics.
