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…
Degradation of superconducting properties in MgB2 films by exposure to water
H Y Zhai, H M Christen, L Zhang +3
The effect of water exposure on MgB2 is studied by submerging an 800 nm thick MgB2 film into deionized water at room temperature for 1 hour, 4 hours, 10 hours, and 15 hours, and by…
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…
