| Research Abstract |
We investigated the superconducting nature in the heavy-fermion systems, using the microscopic NMR/NQR method. We confirmed the strong coupling between the superconducting and antiferromagnetic order parameter around the tetracritical point, suggesting the close relationship between the superconductivity and the antiferromagnetic interactions. The present results give us a lot of important knowledge to theoretically solve the superconducting mechanism in the heavy ?fermion systems.
