Structural, magnetic, and electrical property of nanocrystalline perovskite structure of iron manganite (FeMnO3)In this work, nanostructure FeMnO 3 perovskite material was synthesis by sol–gel auto combustion method using the glycine as a chelating agent for the first time in the literature. The ...
The compound FeMnO3 crystallizing in the mineral bixbyite structure has been prepared by mechanochemical synthesis achieved by high energy ball milling of starting compounds. The structure and magnetism have been studied using powder neutron diffraction and magnetization measurements. Magnetization measurements...
Iron manganite (FeMnO3) powder with a cubic (bixbyite, Ia3-) crystal structure was obtained by a solid state reaction. Thick film paste (powder+organic vehicles) was screen printed on alumina substrate with test interdigitated PdAg electrodes. Significant porosity (60.6%) composed of macropore...
