Abstract

Abstract : In this communication, we report a facile strategy to chemically synthesize anisotropic SmCo5 nanomagnets with a large magnetic energy product (BH). Abstract : In this communication, we report a facile strategy to chemically synthesize anisotropic SmCo5 nanomagnets with a large magnetic energy product (BH). First, we designed a Co3 O4 @Sm2 O3 –CaO precursor by a one-pot method, which could be further reduced into uniform single-crystal SmCo5 particles under the stabilization of CaO coating. Following that, CaO was removed under an oxygen-free environment to impede oxidation. Finally, 130 ± 10 nm SmCo5 particles were aligned to be nanomagnet, exhibiting a large (BH)max value of 18.1 MGOe, which is the highest value reported by chemical methods.
