Magnetic and Structural Properties of Shock-Synthesized Zinc Ferrite

摘要

High-pressure shock-wave loading on stoichiometric mixtures of zinc oxide and ferric oxide powders produces partial conversion to a spinel structure zinc ferrite as shown by x-ray diffraction. The ferrite phase is characterized by a substantial saturation magnetization plus a high-field susceptibility. Since stoichiometric ZnFe sub 2 O sub 4 is paramagnetic above 10 degrees K, the magnetic behavior of the shock-synthesized spinel demonstrates that it is a zinc-deficient ferrite. X-ray diffraction data confirm that less zinc oxide is consumed than ferric oxide in producing the recovered spinel. (ERA citation 10:000958)
