Research Abstract |
In this study, the synthesis and crystal growth methods of target compounds were developed. Characterization of the compounds were carried out using various techniques such as elemental analyses, magnetic property measurements, optical measurements and so on. The samples characterized well, were used for diffraction studies using high-angular resolution powder diffractometer installed at NIMS beamline, SPring-8.Then, I could successfully raise many achievements on this study including related compounds.
