Thermodynamic and transport properties of single-crystalline UMGa5 (M=Fe,Co,Ni,Ru,Rh,Pd,Os,Ir,Pt)

We report the results of magnetic susceptibility, specific heat, and electrical resistivity measurements on UMGa5 (M=Fe,Co,Ni,Ru,Rh,Pd,Os,Ir,Pt) single crystals. Antiferromagnetic ordering was observed for M=Ni, Pd, and Pt, with ordering temperatures TN=80K, 28K, and 23.5K, respectively. For the UMGa5 compounds with transition metals from the Fe and Co columns, itinerant paramagnetic behavior is observed. The evolution of this behavior is discussed in terms of f-ligand interaction with an emphasis on the role played by f-d hybridization. © 2005 The American Physical Society.
