Synthesis, structures and magnetic properties of Pr-lean Pr2Fe14B/Fe3B nanocomposite alloys

► Lean rare-earth PrFeB nanocomposite alloys were studied. ► Addition of Ti leads to enhancement of the coercivity and grain refinement. ► Magnetization reversal behaviors of Pr2Fe14B/Fe3B alloys were discussed. ► Occurrence of a stronger exchange-coupling interaction for Ti-doped samples.
