Properties of MgB2 Films Grown at Various Temperatures by Hybrid Physical-Chemical Vapour Deposition
K. Chen, M. Veldhorst, C. H. Lee +5
A Hybrid Physical-Chemical Vapour Deposition (HPCVD) system consisting of separately controlled Mg-source heater and substrate heater is used to grow MgB2 thin films and thick film…
Effect of damage by 2-MeV He ions and annealing on Hc2 in MgB2 thin films
R. Gandikota, R. K. Singh, J. Kim +9
The effect of damage induced by 2-MeV alpha particles, followed by annealing, on the critical temperature (Tc), resistivity, and upper critical field (Hc2), of three MgB2 films mad…
Upper Critical Fields up to 60T in Dirty Magnesium Diboride Thin Films
C. Ferdeghini, V. Ferrando, C. Tarantini +11
Upper critical fields of several magnesium diboride thin films were measured up to 28 T at the Grenoble High Magnetic Field Laboratory (GHMFL) in Grenoble and up to 60 T at the Lab…
Effect of damage by 2-MeV He ions on the normal and superconducting properties of magnesium diboride
R. Gandikota, R. K. Singh, J. Kim +8
We have studied the effect of damage induced by 2-MeV alpha particles on the critical temperature, Tc, and resistivity of MgB2 thin films. This technique allows defects to be contr…
Electron scattering dependence of dendritic magnetic instability in superconducting MgB2 films
Z. X. Ye, Qiang Li, Y. F. Hu +5
Magnetic instability in both ultra-pure and carbon-doped MgB2 films is investigated by magneto-optical imaging, transport and bulk magnetization measurements. In the carbon-doped M…
Properties of MgB2 thin films with carbon doping
A. V. Pogrebnyakov, X. X. Xi, J. M. Redwing +10
We have studied structural and superconducting properties of MgB2 thin films doped with carbon during the hybrid physical-chemical vapor deposition process. A carbon-containing met…
