Abstract

PrOs₄Sb₁₂ is the first Pr-based heavy fermion superconductor exhibiting intriguing behavior both in the superconducting and normal states. To clarify the origin of the behavior, intensive studies have been made by variety of experimental techniques. As a result of intensive studies, the normal state properties have been mostly clarified, however, there still remain important questions on the superconducting state of this material. We discuss the present status of the understanding of superconducting state in relation with the normal state properties of this material.
