Abstract
- The samples of Bi2Sr2Ca2Cu3-xMnxO10+δ (x = 0.0 to 0.30) were prepared by the standard solid-state reaction method. The phase identification characteristics of synthesized (HTSC) materials were explored through powder X-ray diffractometer reveals that all the samples crystallize in orthorhombic structure with lattice parameters a = 5.4053 Å, b = 5.4110 Å and c = 37.0642 Å up to Mn concentration of x = 0.30. The critical temperature (Tc) measured by standard four probe method has been found to depress from 108 K to 70 K as Mn content (x) increases from 0.00 to 0.30. The effects of sintering temperature on the surface morphology of Bi2Sr2Ca2Cu3-xMnxO10+δ have also been investigated. The surface morphology investigated through scanning electron microscope and atomic force microscopy (SEM & AFM) results that voids are decreasing but grains size increases as the Mn concentration increases besides, nanosphere like structures on the surface of the Mn doped Bi2Sr2Ca2Cu3-xMnxO10+δ (Bi-2223) samples.
