Abstract

Nano-size Bi_1.8Y_1.2Fe₅O₁₂ particles were prepared with a coprecipitation and heat treatment method. The coating films of the particles were prepared with coating techniques. The crystalline sizes of the Bi_1.8Y_1.2Fe₅O₁₂ particles were calculated using the Scherrer equation with the X-ray diffraction data. The calculated size of the 0 h milling particle is about 400 nm that is almost the same as the measured size with a transmission electron microscope. The calculated particle size after 100 h milling is about 50 nm that is almost the same as the measured size with an atomic force microscope. The size of the prepared Bi_1.8Y_1.2Fe₅O₁₂ particles is changed with the milling process. The crystalline size calculation using the Scherrer equation with the X-ray diffraction data is a method of a size estimation of nano-size Bi_1.8Y_1.2Fe₅O₁₂ fine particles
