Magnetic Properties of Non-Stoichiometric UNiGa

Magnetization measurements of alloys based on the intermetallic compound UNiGa with deviation from the exact 1:1:1 stoichiometry, namely Ux(Ni0.5Ga0.5)3-x with 0.8 ≤ x ≤ 1.2 and UNi1.1Ga, have been performed. The obtained results suggest that the antiferromagnetic ground state of UNiGa can be easily transformed into a ferromagnetic one not only by external magnetic fields but also by changes of the composition. © 1995.The work was supported in part by the International Science Foundation (grant RG-1000) and by the Grant Agency of the Czech Republic (Project no. 202/93.0184)
