Synthesis, microstructure and magnetic properties of Heusler Co2FeSn nanoparticles
2013
Heusler Co2FeSn nanoparticles in a B2-type cubic structure were synthesised for the first time using a simple solution reduction method. X-ray diffraction, a scanning electron microscope, an energy dispersive spectrometer and a vibrating sample magnetometer were used to characterise the synthesised products. The crystal structure and composition of the samples vary with the concentration of potassium hydroxide, synthesis temperature and reaction time. Magnetic measurement reveals that the obtained Co2FeSn nanoparticles are soft magnetic at room temperature. The Co2FeSn nanoparticles synthesised in this work are magnetically superior and economically feasible for spintronic applications.
