Abstract
We have investigated the magnetic properties of liquid‐quenched Pr15 (Fe1−x Cox )77 B8 over the whole range of Co concentrations. The coercivity Hci and the remanence Jr depend on the Co content in the same way as in Nd15 (Fe1−x Cox )77 B8 . For the ternary Pr‐Co‐B a high Hci , as large as 15.2 kA/cm, has been obtained. In Co‐rich alloys the temperature dependence of Hci and Jr is limited by the spin reorientation at temperatures well below the Curie point. Except for Pr15 Co77 B8 , annealing of overquenched ribbons leads to substantially lower coercivities. The possible microstructural origin of the magnetic hardening is discussed.Keywords
