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...
متن کاملMagnetic 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...
متن کاملMagnetic 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...
متن کاملHeusler compounds with perpendicular magnetic anisotropy and large tunneling magnetoresistance
In the present work we suggest a recipe for finding tetragonal Heusler compounds with perpendicular magnetic anisotropy (PMA) that also exhibit large tunneling magnetoresistance (TMR) when used as electrodes in magnetic tunnel junction devices with suitable tunneling barrier materials. We performed density-functional theory calculations for 286 Heusler compounds and identified 116 stable tetrag...
