Abstract
The correlation between the structure, chemical composition, electrical and magnetic properties of Bi2Sr2CaCu2O8+δ single crystals is presented. As revealed by SEM measurements, the small samples (approximately 1 mm×1 mm×0.2 mm) are stacks of thin plates (1–2 μm). Microcompositional measurements (energy dispersive spectroscopy) show the Bi2Sr2CaCu2O8+δ (2212)-phase and a small quantity of residual phases enriched in bismuth and strontium and calcium-deficient. Magnetically modulated microwave absorption measurements (MAMMA) lead to a value for the anisotropy of the upper critical field of about 7, which is more than twice the reported value for YBa2Cu3O7-δ single crystals (also determined from MAMMA responses). The plot of the resistance versus temperature suggests that only the first 10–20 plates from the surface of the sample have a contribution to the sample conductivity. The imaginary part, X″, of the magnetic susceptibility of our samples shows three peaks.
