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