Abstract

The magnetic and structural properties of quaternary RCo_4-xFe_xB alloys with R=Nd, Sm, Er have been examined with magnetometry and x-ray diffraction. The CeCo₄B-type phase is found for all x in Er, for x≤3 in Sm, and for x=0, 1, and 2 in Nd. Maximum coercivities have been obtained in a crystallized SmFe₂Co₂B sample with H_c>17 kOe at room temperature.
