| Outline of Final Research Achievements |
Despite numerous studies on high-Tc cuprate superconductors, the detailed relationship between magnetic correlations and the superconductivity has not been clarified yet. The present project aimed to reveal the detailed magnetic correlations in the electron-doped cuprate superconductors R2-xCexCuO4 (R = Pr, Nd, Eu). First, it has been revealed that a small amount of substitution of a magnetic impurity Fe3+ works well on enhancing the weak magnetic signals of the present samples. Then, an existence of dynamically fluctuating magnetic state is revealed to be realized in a wide temperature region above the magnetic ordered state in the R2-xCexCuO4 system. This result shed new light on the electron-hole asymmetry of the high-Tc superconductivity.
