| Outline of Final Research Achievements |
The creation of new materials that give rise to novel quantum properties will make a significant contribution to the development of both basic and applied investigations in solid state physics and chemistry, and will lead to breakthroughs in the research field. In this study, foreign and Japanese researchers collaborate to investigate and synthesize a new group of itinerant electron transition metal compounds that exhibit exotic itinerant electronic properties by combining the frustrate effect, low dimensionality and structural phase transitions, to clarify both macroscopic and microscopic aspects of their new itinerant electronic properties, and to analyze and feedback the experimental results. The aim was to establish a solid-state chemistry basis by analyzing and feeding back the experimental results. As a result, new compounds with several interesting physical properties were created and their novel properties were elucidated.
