Abstract:Magnetic topological insulators novel nano-crystallites Fe1.4Bi0.6Se2.5Y0.5Prx (x= 0.0, 0.1, 0.2 and 0.3) were prepared successfully by acidic Sol at 600°C. Gel technique. The X-ray diffraction pattern shows the higher crystallinity similar to Fe1.4Bi0.6Se3Y nanostructure. Scanning electron microscopy shows there is a combination of small and large nanoparticles in soft accumulation of the samples. The average particle nano-size is nearly 20 ~100 nm. Thermal analysis shows there are a weight loss at 450°C corr… Show more
