• A series of Cr_<23>C_6-type borides was investigated by means of thermomagnetic measurements. The atomic magnetic moment (Curie temperature) of (Fe, Co)_<20>Al_3B_6 increases linearly from about 0.6 Bohr magnetons (403°K) for Co_<20>Al_3B_6 to a value of 1.5 Bohr magnetons (815°K) for Fe_3Co_<12>Al_3B_6. Partial replacement of the Ni in non-magnetic Ni_<20>Al_3B_6 by Fe also causes a smooth increase in moment (Curie temperature) and gives a value of 0.5 Bohr magnetons (285°K) for Fe_3Ni_<12>Al_3B_6. (Co, Ni)_<20>Al_3B_6 exists in a perfect solid solution and shows a peak in moment (Curie temperature) vs. composition curve at about Co_<17>Ni_3Al_3B_6. These results can be accounted for in terms of an idea in which new magnetic moment is induced in these systems.
