Basic properties and possible high superconducting anisotropy of MgB_2 sintered powders and wire segments

摘要

We will briefly outline recent work done by the Ames Laboratory group and collaborators on synthesis and physical properties of newly discovered intermetallic superconductor, MgB_2 (T_c ≈ 40 K), produced in the form of sintered powder and wire segments with the emphasis to be on recent results that indicate that MgB_2 may well have significant anisotropies associated with the superconducting state.
