摘要

•Hf addition stabilizes the 1:7H phase.•Grain refinement is achieved by B addition.•The maximum coercivity (Hc) of the ribbons is achieved at Hf ≃ 3 at.%.•The remanent magnetization increases with increasing B content.•Experimental observations are in conformity with our theoretical calculations.
