“…In previous studies of U doped CeAl 2 using resistivity and susceptibility measurements [9], we have found that hybridization increases with U doping in CeAl 2 and the Néel temperature too; (Ce 0.8 U 0.2 )Al 2 has an antiferromagnetic transition at 6 K. At the same time, it was also shown that the coherence temperature increases with U doping.…”

“…All samples have been made using an arc furnace under Ar atmosphere as described previously [9]. Since there is a miscibility gap from x = 0.3 to 0.7 for (Ce 1−x U x )Al 2 , we have only made (Ce 1−x U x )Al 2 with x = 0, 0.05, 0.1, 0.2, 0.8, 0.9 and 1.…”

“…Subsequently, they have been subjected to heat treatments. The Ce rich samples have been annealed at 800 • C for two days and at 873 • C for five days, while the U rich samples have been kept at 850 • C for five days as described before [9].…”

We have studied the thermopower of U doped CeAl 2 and Ce and La doped UAl 2 . Despite different ground state properties of CeAl 2 and UAl 2 , the former being an antiferromagnetic heavy-fermion compound and the latter non-magnetic, we have found that not only thermopower data for pure CeAl 2 and UAl 2 are similar but also the thermopower results of doped samples behave similarly. Although the similarity seen in pure systems is yet to be understood, we interpret the doping effects as the results of changes in energy dependent relaxation time with doping.

Our studies show that hydrostatic pressure causes a substantial increase in Kondo temperature TK and suppresses the magnetic order of the Ce-rich side of (Ce,U)Al2. For example, the magnetic transition of (Ce0.7U0.3)Al2 disappears above 5.5 kbar. Spin fluctuations dominant in the U-rich side become suppressed too, and simultaneously the U-rich systems are driven with pressure towards a simple metallic regime. A new scaling is found of the pressure-dependent resistivity of U-rich samples.

“…It is also known that the multi-valence-states of Ce can lead to richer phases of Ce-based intermetallic compounds. For example, for the Ce-Al binary compounds, crystalline phases of Ce 1 Al 1 , 22 Ce 1 Al 2 , 23 Ce 1 Al 3 , 24 Ce 1 Al 4 (ref. 25) and Ce 3 Al 1 (ref.…”
