Pressure-induced superconductors on heavy fermion system

Abstract

Since the discovery of a heavy fermion superconductor CeCu2Si2 in 1979, heavy fermion superconductivity has been observed in several rare earth and actinide compounds. Especially the development of high pressure technique and crystal growth makes it possible to investigate the pressure-induced superconductivity in the heavy fermion compounds, possessing magnetic ordering at ambient pressure. In this article, we present recent advances in pressure-induced superconductivity around antiferromagnetic fluctuation, focusing on CeRhIn5 and CeIrSi3.
