Abstract

The superconducting nanocrystalline ceramic powder Fe2Mn2Ni2Zn2O11was designed and fabricated by a high temperature special furnace. In the area of ceramic superconductors, particle size is an important factor. Here the authors analyze the particle size and strain of the nano crystalline 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 a=ß=?=900. 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
