AbstractNanocapsules consisting of B2O3/H3BO3 encapsulating Fe-Gd cores have been synthesized by an arc-discharge process using metal-boron alloys as cathode. Most of the nanocapsules have a well-constructed shell/core structure with a uniform B2O3/H3BO3 shell. Heat-treatment induces reactions between the shell and the core, resulting in the formation of a Fe3BO5+GdBO3 matrix embedded with Fe nanoparticles, reduction of the metallic-core size and decrease of the blocking temperature T-B. Above T-B, the magnetization curves plotted vs. H/T overlap and show zero coercivity. Below T-B, the coercivity shows a linear dependence when plotted vs. T-1/2. However, the coercivity-T-1/2 curve below 60 K has a different slope from that above 60 K, indicating the existence of two different magnetic phases in the nanocapsules. Different from bulk Fe3BO5, nanoscale Fe3BO5 particles have a lower transition temperature to the weak-ferromagnetic state. and magnetic hysteresis is absent due to size effects.
