Measurements of the temperature dependence of the surface resistance at 3 GHz of 100 micron size fragments of MgB2 separated powder are presented and discussed. The microwave surface resistance data are compared to experimental results of Nb, Bi2Sr2CaCu2O8+δ (BSCCO) and theoretical predictions of s-wave weak coupling electron-phonon theory (BCS).

Abstract
Measurements of the temperature dependence of the surface resistance at 3 GHz of 100 micron size fragments of MgB2 separated powder are presented and discussed. The microwave surface resistance data are compared to experimental results of Nb, Bi2Sr2CaCu2O8+δ (BSCCO) and theoretical predictions of s-wave weak coupling electron-phonon theory (BCS).File in questo prodotto:
