Abstract

Abstract: In this work, we investigated the influence of concentration of the additional nanoparticles of and on the coercivity of the sintered magnets. Composition and concentration of the additional compounds clearly influence magnetic properties of the magnets. The coercivity increases linearly from to with increasing the weight fraction of the nanoparticles from 0 to . Meanwhile, the of the added magnets reaches a maximal value of at the optimum addition of . The quite high maximum energy products, , were also obtained for the magnets added with the nanoparticles.
