Abstract

The superconducting nanocrystalline ceramic powder Fe2Mn2Ni2Zn2O11 was designed and fabricated by a high-temperature special furnace. In the area of ceramic superconductors, particle size is an important factor. Here the authors analyzed the particle size and strain of the nanocrystalline ceramic super conducting material. The sample was analyzed by X-ray Diffraction (XRD), particle size determination, SEM and EDX. The comparison of XRD results with JCPDS files confirmed the orthorhombic structure of the sample with a≠b≠c and α = β = γ = 90°. Scanning electron microscopy (SEM) studies revealed that its particle size is in the nanometer range. It also confirmed the calculated value of particle size from Debye Scherrer’s formula. EDX spectrum shows the elements of the sample. X-ray instrumental peak broadening analysis was used to evaluate the size and lattice strain by the Williamson-Hall Plot method. Keywords: Ferromanganesenickelzincoxide (FeMnNiZnO), XRD, Debye Scherrer’s formula, instrumental broadening, Williamson-Hall Plot method, SEM, EDX, particle size
