Constitution of iron-germanium system is discussed based on x-ray and magnetic studies, and a new phase diagram is proposed. Fe solid solution (α) ranges up to 20.4 at.% Ge at 710℃ and to 21.3 at.% Ge at 520℃. Homogeneity range^- of the most iron rich compound (ε above 700℃and ε_1 below) are 23.8-26 at.% Ge at 710℃ (ε) and 24.2-25.8 at.% Ge at 580℃ (ε_1). At 50 at.% Ge, ξ phase has a narrow range below 700℃. In α (b.c.c.) solid solution of iron, the saturation magnetization and Curie point decrease to 150 emu/g and 885°K respectively. Crystal structures of ε and ε_1 phases are Ni_3Sn(D0_19) and Cu_3Au(L1_2) type, and the saturation magnetization of both phases is about 150 emu/g, while tlle Curie points are 650°K for ε and 760°K for ε_1. ζ Phase has CoSn (B35) type of structure and is paramagnetic, the moment being 2.8μ_B /Fe. Magnetic interaction and magnetic structures are also discussed.
