Research Abstract

This project was aimed to develop new materials for four years with various types of magnetism and phase transition on the basis of rare earth manganites which have been studied for many years by the authors. The unique point of this project is application of adjustment technique of oxygen partial pressure to control valence state of manganese, which affects magnetic interaction and phase transition based on the tilting model of oxygen octahedra of the crystal structures. Our group has established this unique technique. Several new materials of Ln_2MnTiO_6(Ln=rare earth) were successfully synthesized under low oxygen partial pressure at high temperature. These have three kinds of crystal structures and unique magnetic interaction between long distant ions. Another new materials of rare earth manganites containing precious metal elements with perovskite structure were also developed, which have phase transition at high temperature and magnetism from a combination of antiferromagnetic an … More d ferromagnetic interactions between magnetic ions. New types of phase transition were further discovered for some rare earth manganites with layered perovskites such as BaLn_2Mn_2O_7 and (Ca,Ln)_2MnO_4 (Ln=rare earth) at high and low temperature. These phase transitions were characterized by tilting model of mutual oxygen octahedra inside the structure from the results of high and low temperature X-ray diffractometry and electron diffraction analysis and high resolution electron microscopic study. Single crystal characterization method became useful to clarify phase behavior in this project after annealing single crystal under various heat treatment conditions for refinement to determine the crystal structures. Other types of new materials with pyrochlore-related structure were also successfully synthesized and their crystal structures were characterized by several methods as mentioned above. Thus new results were obtained from this project and these results are now published in international academic journals. Less
