Abstract
The effect of additive Ga on the microstructure and magnetic properties ofnanocomposite Pr2(Fe,Co)14B/α-(Fe,Co) ribbons has been investigated. One per cent Ga addition was found toimprove significantly its magnetic properties. The remanence and maximumenergy product increase from 1.14 T, 17 MG Oe for Ga-free samples to 1.22 T,22.2 MG Oe for Ga-doped samples. The significant improvements of magneticproperties originate from the refinement of the grains of the samples byintroducing Ga, which leads to a stronger exchange coupling between themagnetically hard and soft phases in comparison with that inGa-free samples.
