Some intermetallic compounds which contain uranium or cerium present heavy fermion characteristics. Take, for example, in the UM 2 Al 3 ( M = Pd , Ni ) family, superconductivity and magnetism coexist and present heavy fermion behavior. This work presents the crystallographic characteristics and physical properties of a new compound of this family; the intermetallic compound UCo 2 Al 3. Our initial crystallographic studies performed in a small single crystal show that the structure is hexagonal and similar to the UNi 2 Al 3 and UPd 2 Al 3 parent compounds. The space group is P6/mmm with a=5.125 Å and c=4.167 Å crystalline parameters. Measurements of resistivity and magnetization performed on the single crystal reveal that the compound is not superconducting when measured at about 1.8 K. The compound is highly anisotropic and features related to Kondo-like behavior are observed. A weak ferromagnetic transition is observed at a temperature of about 20 K.

Heavy Fermion Behavior

Based on band structure, total and projected density of states and Mulliken Population Analysis, the electronic properties of CeOs 4 Sb 12 were investigated. The calculated energy bands depict a semiconductor behavior with an energy gap (direct gap at H ) of the order of 0.45 eV. On the other hand, a strong hybridization occurs between Ce f-orbitals with Os d-, p-, and Sb p-orbitals, which convince us to believe that this hybridization, added to the existence of a mini gap, are responsible for the heavy Fermion behavior, as well as the possibility to consider it a candidate for thermoelectric applications.
