MAGNETIC STRUCTURE AND TRANSITION OF AMORPHOUS Nd_x Ni_1-x THIN FILMS

The magnetic of Nd_x Ni_1-x, amorphous thin films were studied. It was found that the effective magnetic moment of Ni atom (μ_Ni) approached to zero at X 0.26, and when X < 0.26 the composition dependence of μμ_Ni followed approximately μ_Ni = (0. 6-3X^1.2) μ_B It is found that the aspermagnetic and speromagnetic structures coexist in the amorphous Nd-Ni films with X < 0.26, and only speromagnetic structure exists for X < 0.26.
