O sample was analyzed with X-ray diffraction
and only ZnO diffraction peaks can be found with doping concentration lower than 6.66%. An increase in the hexagonal lattice parameters of ZnO is observed on increasing the Fe concentration.
M-T
curve of the powder material was measured with Superconducting Magnet System
the magnetic loop can be observed at the temperature of 10 K.
