Abstract :
Nano-size Bi1.8Y1.2Fe5O12 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 Bi1.8Y1.2Fe5O12 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 Bi1.8Y1.2 Fe5O12 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 Bi1.8Y1.2Fe5O12 fine particles
