| Outline of Final Research Achievements |
In recent years, applications of magnetic nanoparticles in various fields are expected. We found that LaFeO3 nanoparticles having almost no magnetization in bulk form showed large magnetization at low temperatures. Therefore, it should be worth to clarify the mechanism of the induced magnetization systematically to evaluate the relationship between the crystal structure and magnetic properties of LaFeO3 nanoparticles. As a first step, we tried to prepare LaFeO3 nanoparticles with a uniform particle size distribution by using salt-assisted spray pyrolysis. The salt-assisted spray pyrolysis has been expected to synthesize complex oxide nanoparticles with single nanometric sizes.
