Abstract

We recently discovered that the intermetallic compound magnesium diboride (MgB₂) exhibits the highest superconducting transition temperature (T_c = 39 K) of all the metallic superconductors. In this paper we report on the basic superconducting characteristics of MgB₂ and the current status of the research for the unanswered problem in this superconductivity. Especially, we review the several reports for the superconducting gap (Δ) by the spectroscopic measurements. Moreover we introduce the research into its anisotropic parameter (γ), which is important for the understanding of this superconducting states in this material.
