| Abstract: Magnetization density , neutron diffraction and a spin polarized have been made on uranium compounds , Upt3 , UB13 . The compounds containing Pt , crystallizes in the hexagonal N13Sn structure the space group P.3 / mmc . The Heavy Fermion Compound UBe13 crystallizes in the cubic NaZn , structure with the space group Fm 3 c . In addition to the investigation of the nuclear structures of two compounds the influence of the magnetic degrees of freedom on the physical properties has been investigated . For Up the conduction electron play an important role . It is to be expected that band structure effects significantly determine the properties of Up , at low temperature . In contrast for UBe 13 the conduction electron density of states is found to be significantly smaller that in Up . As the density of states at the Fermi level is predominately of 5f electron character in UB13 , this Heavy Fermion system is easier to model magnetically compared to Up₁3 | ||
