Present work describes the magnetic properties of Nd-Fe-B melt-spun ribbons which have lower Nd content than the Nd₂Fe₁₄B compound. The studied alloys were (1) Nd_xFe_94-xB₆, (2) (Fe₃B)_1-x-(Nd₂Fe₁₄B)_x and (3) Fe_1-x-(Nd₂Fe₁₄B)_x. The grain refinement were underwent by studying the conditions of annealing for crystallization. It results in disappearing noticeable knicks in the demagnetization curves, which is attributed to precipitations of &alpha;-Fe and Fe₃B phases. The Nd₈Fe₈₆B₆ melt-spun ribbon annealed at 650&deg;C for 30 min exhibits the highest (<i>BH</i>)_max of 126kJm^-3(15.8MGOe). The V addition is effective for improving the coercivity.
