| Research Abstract |
We have investigated the relationship between heavy fermion superconductivity and magnetism, especially in the noncentrosymmetic pressure-induced superconductor CeIrSi_3. Antiferromagnetism disappears and superconductivity appears around 2 GPa in CeIrSi_3. The antiferromagnetism is induced by applying the magnetic field, and the antiferromagnetism competes with superconductivity. The superconducting upper critical field H^<c2> is suppressed in the field-induced antiferromagneic phase. With increasing pressure the field-induced antiferromagnetic phase moves to very high magnetic field and the H^<c2> is extremely enhanced.
