Pressure and chemical substitution effects in the local atomic structure of BaFe2As2
E. Granado, L. Mendonca-Ferreira, F. Garcia +10
The effects of K and Co substitutions and quasi-hydrostatic applied pressure (P<9 GPa) in the local atomic structure of BaFe2As2, Ba(Fe{0.937}Co{0.063})2As2 and Ba{0.85}K{0.15}Fe2A…
Columnar defects acting as passive internal field detectors
A. V. Silhanek, L. Civale, M. A. Avila
We have studied the angular dependence of the irreversible magnetization of several YBaCuO and 2H-NbSe single crystals with columnar defects tilted off the c-axis.…
Irreversible magnetization under rotating fields and lock-in effect on ErBa_2Cu_3O_7 single crystal with columnar defects
M. A. Avila, L. Civale, A. V. Silhanek +3
We have measured the irreversible magnetization M_i of an ErBa_2Cu_3O_7 single crystal with columnar defects (CD), using a technique based on sample rotation under a fixed magnetic…
Angular dependence of the bulk nucleation field Hc2 of aligned MgB2 crystallites
O. F. de Lima, C. A. Cardoso, R. A. Ribeiro +2
Studies on the new MgB2 superconductor, with a critical temperature Tc ~ 39 K, have evidenced its potential for applications although intense magnetic relaxation effects limit the…
Anisotropic superconducting properties of aligned MgB2 crystallites
O. F. de Lima, R. A. Ribeiro, M. A. Avila +2
Samples of aligned MgB2 crystallites have been prepared, allowing for the first time the direct identification of an upper critical field anisotropy Hc2^{ab}/Hc2^{c}= xi_{ab}/xi_{c…
Anomalous behavior of the irreversible magnetization and time relaxation in YBaCuO single crystals with splayed tracks
A. Silhanek, D. Niebieskikwiat, L. Civale +3
We have studied the angular dependence of the irreversible magnetization and its time relaxation in YBaCuO single crystals with one or two families of columnar defects…
