Pulsed Laser Deposition of YBCO for Coated Conductor Applications: Current Status and Cost Issues
Hans M. Christen
This book chapter reviews the current status of Pulsed Laser Deposition (PLD) for coated conductor applications of YBCO on metallic tapes. Clearly, PLD is one of the most promising…
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…
Unusual Hall Effect in Superconducting MgB Films: Analogy to High-T Cuprates
R. Jin, M. Paranthaman, H. Y. Zhai +3
We have investigated the temperature and magnetic field dependence of the Hall coefficient of two well-characterized superconducting MgB films (T=38.0 K) in both the nor…
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…
