Raman scattering, X-ray photoemission spectra and superconductivity of a tiny Ag diffusion to MgCNi3
Fa-Min Liu, J. Q. Li, C. Dong +3
The tiny Ag diffusion to MgCNi3 has been prepared by solid states reaction. Its structure was characterized by X-ray diffractometer (XRD). The results show that a small mount of Ag…
X-ray photoemission study of polycrystalline Mg(1-x)Al(x)B(2)
Fa-Min Liu, C. Dong, J. Q. Li +1
Polycrystalline Mg(1-x)Al(x)B(2) (x = 0, 0.1, 0.4, 0.5, 0.6, 1) samples have been prepared by a conventional solid state reaction. The Mg 2p, Al 2p and B 1s core level binding ener…
Preparation and Superconductivity of a MgB2 Superconducting Tape
G. C. Che, S. L. Li, Z. A. Ren +8
A MgB2 superconducting tape has been successfully prepared by a new way of boron diffusion into Mg tape. This tape superconductor has a Tc of 39 K with a sharp transition width of…
Superconductivity and Aluminum Ordering in Mg1-xAlxB2
J. Q. Li, L. Li, F. M. Liu +3
Superconductivity and structural properties of Mg1-xAlxB2 materials have been systematically investigated. Evident modifications in both superconductivity and microstructure are id…
