Synthesis, characterization, crystallization kinetics of amorphous Fe_74.5Zr_8.5B₁₇ magnetic nanoparticles, and magnetoelectric properties of Fe_74.5Zr_8.5B₁₇/BaTiO₃ composite

This work reports the facile synthesis ofamorphous Fe74.5 Zr8.5 B17 magnetic nanoparticles (MNPs) through a simple NaBH4-assisted chemical reduction method. The obtained MNPs were characterized in terms of amorphous/crystal structure, morphology, magnetic properties, composition, and crystallization kinetics. The saturation magnetization value was determined as 57.83 emu/g. The crystallization peak temperatures (Tp) and activation energy were determined to be 467.18 degrees C and 294 kJ/mol, respectively. Additionally, the FeZrB MNPs were combined with the BaTiO3 NPs via ball milling at low speed, using a mass ratio of 30/70%, respectively and the magnetoelectric coefficient value for FeZrB/BaTiO3 composite measured at a 1 kHz AC magnetic field is approximately 8.9 mV/Oe/cm. The study outcomes may provide a platform of nanotechnology for the preparation of MNPs with adjustable properties, which will be promising for practical applications.
