摘要：

Measurements of 10 GHz microwave surface resistance, R-s, of dense MgB2 wire and pellet are reported. Significant improvements are observed in the wire with reduction of porosity. The data lie substantially above the theoretical estimates for a pure Bardeen-Cooper-Schrieffer s-wave superconductor. However, the R-s (20 K) of the wire is an order of magnitude lower than that of polycrystal YBa2Cu3O6.95 and matches with single-crystal YBa2Cu3O6.95. The results show promise for the use of MgB2 in microwave applications. (C) 2001 American Institute of Physics.
