  Article:   MAGNETIC PROPERTIES OF U(FEXSI1-X)2 COMPOUNDS.

Authors:  ILEANA LUPSA.
 
       
         
  Abstract:  The magnetic behaviour of the U(FexSi1-x)2 compounds with x=0.25, 0.5 and 0.75 was discussed The magnetic properties of U2Fe3Si compound reveal the spin fluctuations behaviour. The magnetic properties were discussed using the hybridization matrix elements which describe the interaction between uranium f and d and p orbitals. The total covalent energy according to the criterion of localized uranium moments is compared with the critical energy and the magnetic ordering presence may be established.
