Improved superconducting properties in nanocrystalline bulk MgB_2
A. Gümbel, J. Eckert, G. Fuchs +3
Highly dense nanocrystalline MgB_2 bulk superconductors with distinctly improved pinning were prepared by mechanical alloying of Mg and B powders and hot compaction at ambient temp…
Specific heat and disorder in the mixed state of non-magnetic borocarbides
D. Lipp, M. Schneider, A. Gladun +7
The temperature and magnetic field dependence of the specific heat cp(T,H) in the superconducting mixed state as well as the upper critical field Hc2(T) have been measured for poly…
Surprises in the doping dependence of the Fermi surface in Bi(Pb)-2212
A. A. Kordyuk, S. V. Borisenko, M. S. Golden +6
A detailed and systematic ARPES investigation of the doping-dependence of the normal state Fermi surface (FS) of modulation-free (Pb,Bi)-2212 is presented. The FS does not change i…
Upper critical field and irreversibility line in superconducting MgB_2
G. Fuchs, K. -H. Müller, A. Handstein +5
The upper critical field Hc2(T) of sintered pellets of the recently discovered MgB_2 superconductor was investigated by transport, ac susceptibility and dc magnetization measuremen…
Fully dense MgB_2 superconductor textured by hot deformation
A. Handstein, D. Hinz, G. Fuchs +5
Bulk textured MgB_2 material of nearly full density showing a weak c-axis alignment of the hexagonal MgB_2 grains parallel to the pressure direction was obtained by hot deformation…
Estimation of matrix element effects and determination of the Fermi surface in BSCCO systems using angle-scanned photoemission spectroscopy
S. V. Borisenko, A. A. Kordyuk, S. Legner +14
The strong dependence of the momentum distribution of the photoelectrons on experimental conditions raises the question as to whether angle-resolved photoemission spectroscopy (ARP…
