Mischmetal of Bayan Obo ore was utilized to prepare the high performance (Pr7.34Nd21.86)1-xMMxFe68.7Al0.1Cu0.12Co0.88B ribbons using melt-spinning method. Phase composition and magnetic properties were investigated at room temperature. The ribbons mainly consist of R2Fe14B phase in isotropic nanostructure. Both coercivity and maximum energy product decrease with the increase of MM content. The magnetic parameters of the ribbons with MM = 20 % in mass are Br = 7.38 kGs, Hcj = 13.66 kOe, (BH)max = 11.81 MGOe. Henkel plots were applied to demonstrate the exchange coupling interaction between grains.
