Microwave Power, DC Magnetic Field, Frequency and Temperature Dependence of the Surface Resistance of MgB2
A. A. Zhukov, A. Purnell, Y. Miyoshi +13
The microwave power, dc magnetic field, frequency and temperature dependence of the surface resistance of MgB2 films and powder samples were studied. Sample quality is relatively e…
Temperature dependence of the microwave surface impedance measured on different kinds of MgB samples
A. A. Zhukov, L. F. Cohen, A. Purnell +11
In this paper we present the results of measurements of the microwave surface impedance of a powder sample and two films of MgB. One film has K and is not textured, th…
Microwave Surface Resistance in MgB2
A. A. Zhukov, K. Yates, G. K Perkins +8
Measurements of the temperature dependence of the surface resistance at 3 GHz of 100 micron size grains of MgB_2 separated powder are presented and discussed. The microwave surface…
Critical currents and vortex dynamics in super-conducting MgB2
Y. Bugoslavsky, G. K. Perkins, X. Qi +2
The recently-discovered MgB2 super-conductor has a transition temperature Tc approaching 40K, placing it intermediate between the families of low and high temperature super-conduct…
