Mn and Bi nanoparticles were synthesized by a wet chemistry reduction process. The as-synthesized Mn and Bi nanoparticles were mixed in hexane with the molar ratio of 1 to 1, and annealed at 250 degrees C in an inert gas environment. In four parallel experiments, the annealing time was controlled to be 2, 4, 6, and 8 h. The impacts of annealing time on product morphology, crystallization, and magnetic properties were investigated. The results showed that within 6 h annealing, an increased annealing time resulted in more sintering among the particles in the products, enhanced crystallization, and improved magnetic properties. When the annealing time exceeded 6 h, further annealing did not bring much difference in morphology, crystallization, and magnetic properties, indicating a thermally stable state of the product.
