Phase transformation resulting from nitrogen annealing of bismuth-deficient-2212 compound
Description
Phase transformation of nominal Bi deficient 2212 has been studied through X-ray diffraction, resistivity and susceptibility. The reversibility of converting the lower Tc phases of Bi system along with Ca2CuO3 and CuO, into high Tc Bi-phase has been observed. The N2 annealing of this distorted Bi-2223 phase leads to the formation of lower Tc phases in the system. Further higher temperature nitrogen annealing of the Bi-2223 phase has been seen to generate the amorphicity in the material. Results are also discussed in the light of recent band structure calculations
