T. Fukami et al., MAGNETIC FIELD-DIRECTION DEPENDENCE OF CRITICAL-CURRENT DENSITY IN C-AXIS ORIENTED BI2SR1.7LA0.3CUO6+Y FILMS, Physica. B, Condensed matter, 194, 1994, pp. 1835-1836
The magnetic field-direction dependence of the critical current densit
y is studied for the copper oxide superconducting Bi2Sr2-xLaxCuO6+y fi
lms prepared by the laser ablation technique. Experimental results are
discussed on the basis of the two dimensional properties of magnetic
flux lines.
