Abstract

Magnetisation studies have been made of pseudobinary compounds Gd(Rh_1-cX_c)₂, X = Mn, Fe and Co, in fields of up to 50 kOe and in the temperature range 4-300 K. For GdRh₂ measurements give T_c = 71 K and μ_s = 7.03 μ_B/f.u. The data for all three series also extrapolate to these values. The substitution of the 3d-atoms for Rh raises the ordering temperature, T_c of the alloys. The initial variations of T_c with Mn and Fe in the Gd(Rh_1-cMn_c)₂ and Gd(Rh_1-cFe_c)₂ series are similar and are much faster than those of T_c in the cobalt substituted compounds. In the Gd(Rh_1-cCo_c)₂ series the molecular moment μ_s shows a slow monotonic decrease with Co content and extrapolates to 4.64 μ_B for GdCo₂. In the Gd(Rh_1-cMn_c)₂ series μ_s decreases almost linearly with Mn content. The rate of decrease being somewhat greater than that of cobalt substituted compounds. At the GdMn₂ end a T_c of approximately 40 K and μ_s of 4.07 μ_B were measured. The fastest variation in both T_c and μ_s occurs in the Gd(Rh_1-cFe_c)₂ series particularly for c < 0.15. In the dilute limit the 3d-atoms are not magnetic.
