Abstract

Structure, magnetic properties and magnetostriction of Tb0.5Pr0.5(Fe0.4+xCo0.6-x)(1.9) (0 less than or equal to x less than or equal to 0.6) alloys are investigated. The existence of the delta phase for 50% Tb and 50% Pr is beneficial to the formation of the MgCu2-type Laves phase. The composition dependence of Curie temperature has the same trend as the Slater-Pauling curve for the moment of Fe-Co alloys. The saturation magnetization M-g and the remanence M-R decrease, whereas the coercivity H-i(c) increases with decreasing Co content, due to the increased amount of the non-cubic PuNi3-type phase. The polycrystalline magnetostriction \lambda parallel to - lambda\ of the alloys at room temperature increases with increasing magnetic field and does not achieve saturation up to 796 kA/m.
