Abstract

Coercivity, magnetization, Curie temperature and maximum energy product of rapidly quenched (Fe_1-xCo_x)_1-y(Sm, Pr)_y (0≤x≤1.0; y=0.11, 0.17 and 0.22) alloys were measured. The coercivity at room temperature is 480-1120 kA/m for (Fe_1-xCo_x)_0.83Sm_0.17 (CaCu₅ type, 0.6≤x≤1.0), 240-480 kA/m for (Fe_1-xCo_x)_0.83Pr_0.17 (CaCu₅ type, 0.6≤x≤1.0), 240-500 kA/m for (Fe_1-xCo_x)_0.78Pr$0.22$/ (Gd₂Co₇ type, 0.6≤x≤1.0) 64-160 kA/m for (Fe_1-xCo_x)_0.89Pr_0.11 (TbCu₇ type, 0≤x≤0.6), and 4-64 kA/m for (Fe_1-xCo_x)_0.89Pr_0.11 (TbCu₇ type 0≤x≤1.0). The magnetic anisotropy and coercivity are discussed on the basis of the single ion model. The composition dependence of coercivity in the (Fe-Co)_0.83Sm_0.17 and (Fe-Co)_0.89Sm_0.11 alloys are attributed to the change in lattice constant and molecular field.
