Abstract

We report the synthesis of the Dy substituted (Nd_0.9Dy_0.1)₂(Fe, Co)₁₄B nanoparticles with a coercivity value of 10.4 kOe, by a "green" and low cost mechanochemical technique. The properties of these (Nd_0.9Dy_0.1)₂(Fe, Co)₁₄B nanoparticles can be improved by magnetic alignment. The remanence (M_r) tripled after alignment, with an average misalignment angle of 34.2°. The thermal coefficient of remanence (α) is -0.12%, comparable to the room temperature value of commercial Nd-Fe-B magnets.
