| Research Abstract |
The research on 2-dimensional itinerant-electron systems has been conducted in order to investigate and to establish novel 2-dimensional itinerant-electron systems by controlling the electronic states of transition-metal elements. As a result, we newly found the itinerant-electron metamagnetic transitions around 60 T in the high-fieldmagnetization process of SrCo2P2. By substituting Ca for Sr, the system was found to approach the QCP of the 2D itinerant ferromagnetism. In the 2-dimensional superconductingsystem Fe(Te-Se), furthermore, physical properties were investigated by utilizing 125Te NMR. Consequently, the mechanism of this superconductivity was found to be due to the antiferromagnetic spin-fluctuation.
