Studies from I. Ahmad et al Have Provided New Data on Materials Science

May 6, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Materials Science are discussed in a new report. According to news reporting from Islamabad, Pakistan, by VerticalNews journalists, research stated, "Single phased nanocrystalline Co0.7Mg0.3FeAlO4 ferrites having low coercivity were synthesized by the sol-gel auto-combustion route. The subsequent powder materials were sintered in a temperature range of 800-1200 degrees C for 2 h. The effects of sintering temperatures on the structure, morphology and magnetic properties of the prepared soft magnetic material were studied."

The news correspondents obtained a quote from the research, "X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and magnetic property measurement system (MPMS) were used to characterize the samples. X-ray diffraction analysis confirmed a single-phase cubic spinel structure and ruled out the presence of impurities like hematite. The higher sintering temperatures have caused in enhanced mark of crystallinity and bigger average grain size of the nanocrystals. A slight decrease in lattice parameters was noticed with a rise of grain size."

According to the news reporters, the research concluded: "Magnetic measurements revealed that grain size increase led to a decrease in the coercivity and, in difference, an increase in the saturation magnetization."
