Investigation of the growth and magnetic properties of highly oriented films of the Heusler alloy Co2MnSi on GaAs(001)
L. J. Singh, Z. H. Barber, A. Kohn +4
Highly (001) oriented thin films of Co2MnSi have been grown on lattice matched GaAs(001) without a buffer layer. Stoichiometric films exhibited a saturation magnetization slightly…
Enhancement of Critical Current Density in low level Al-doped MgB2
A. Berenov, A. Serquis, X. Z. Liao +7
Two sets of MgB2 samples doped with up to 5 at. % of Al were prepared in different laboratories using different procedures. Decreases in the a and c lattice parameters were observe…
Structural, magnetic and transport properties of thin films of the Heusler alloy Co2MnSi
L. J. Singh, Z. H. Barber, Y. Miyoshi +3
Thin films of Co2MnSi have been grown on a-plane sapphire substrates from three elemental targets by dc magnetron co-sputtering. These films are single phase, have a strong (110) t…
Superconducting gap structure and pinning in disordered MgB2 films
Y. Bugoslavsky, Y. Miyoshi, G. K. Perkins +7
We have performed a comparative study of two thin films of magnesium diboride (MgB2) grown by different techniques. The critical current density at different temperatures and magne…
The effect of magnetic field on the two superconducting gaps in MgB2
Y. Bugoslavsky, Y. Miyoshi, G. K. Perkins +4
Double-gap superconductivity in an epitaxial MgB2 film has been studied by means of point-contact spectroscopy in magnetic field up to 8 Tesla. The relatively fast disappearance of…
Effects of proton irradiation and ageing on the superconducting properties of single crystalline and polycrystalline MgB2
G. K. Perkins, Y. Bugoslavsky, A . D. Caplin +7
We present magnetisation data on crystalline and polycrystalline MgB2 before and after irradiation with ~1MeV protons. In the virgin crystal the critical current density is below o…
