Magnetic Properties Of Amorphous Co75-xfexsi15b10 (0 < X < 50)

On amorphous ribbons of the composition Co75-xFexSi15B10 (0 ≤ x ≤ 50) the Curie temperature TC, the saturation magnetization and the magnetostriction constant λS were determined. The concentration dependence of TC was analyzed using a molecular field model. The concentration and temperature dependence of the saturation magnetization was analysed assuming a superposition of the Fe- and Co-moments respectively. λS(x, T) was analysed assuming the existence of a single and a two ion term. © 1992.1161-2154158Madurga, Vázquez, Hernando, Nielson, (1984) Solid State Commun., 52, p. 701Hernando, Influence of the Tensile Stress on the Magnetostriction Resistivity and Magnetic Anisotropy of Co-Rich Metallic Glasses.
