Magnetic and crystallographic structures in UTX intermetallic compounds

Magnetic anisotropy in UTX compounds

We compare results of measurements of magnetization, specific heat, electrical resistivity and neutron diffraction on single crystals and oriented polycrystalline powders of various UTX compounds. Very strong anisotropy, persisting also in the paramagnetic state, is a general feature of these materials. Compounds with the hexagonal ZrNiAl-type structure exhibit, as a rule, a uniaxial anisotropy...

Magnetic Properties and Hybridization Effects in Utx Compounds

Systematic trends in the results of magnetic and specific-heat studies of UTX compounds (T = transition metal, X = p element) are discussed in terms of the degree of the U-Sf electron delocalization which is controlled by the strength of 5f-ligand hybridization. Continuous changes of this parameter and its influence on ground-state properties were investigated in solid solutions of selected UTX...

Hydrogen in R2Fe17 intermetallic compounds: Structural, thermodynamic, and magnetic properties

Revealing Tendencies in the Electronic Structures of Polar Intermetallic Compounds

The quest for solid-state materials with tailored chemical and physical features stimulates the search for general prescriptions to recognize and forecast their electronic structures providing valuable information about the experimentally determined bulk properties at the atomic scale. Although the concepts first introduced by Zintl and Hume–Rothery help to understand and forecast the bonding m...

Magnetic anisotropy in the cubic Laves REFe2 intermetallic compounds

In the past, the Callen–Callen (1965 Phys. Rev. 139 A455–71; 1966 J. Phys. Chem. Solids 27 1271–85) model has been highly successful in explaining the origin and temperature dependence of the magneto-crystalline anisotropy in many magnetic compounds. Yet, despite their high ordering temperatures of ∼650 K, the Callen–Callen model has proved insufficient for the REFe2 compounds. In this paper, w...
