Findings from University of Valencia in the Area of Zinc Oxide Nanotechnology Reported

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanotechnology. According to news reporting out of Valencia, Spain, by NewsRx editors, research stated, "The magnetic properties of Mn-doped ZnO (ZnO:Mn) nanorods grown by hydrothermal process at a temperature of 200 degrees C and a growth time of 3h have been studied. The samples were characterized by using powder X-ray diffraction with Rietveld refinement, scanning electron microscopy, energy-dispersive X-ray analysis and SQUID magnetometry."

Our news journalists obtained a quote from the research from the University of Valencia, "Mn (3wt%) and (5wt%)-doped ZnO samples exhibit paramagnetic and ferromagnetic behavior, respectively, at room temperature. The spin-glass behavior is observed from the samples with respect to the decrease of temperature. At 10K, both samples exhibit a hysteresis loop with relatively low coercivity. The room-temperature ferromagnetism in 5wt% Mn-doped ZnO nanorods is attributed to the increase in the specific area of grain boundaries, interaction between dopant Mn2+ ions substituted at Zn2+ site and the interaction between Mn2+ ions and Zn2+ ions from the ZnO host lattice."

According to the news editors, the research concluded: "M-H curve of hydrothermally grown ZnO:Mn (3wt%) and ZnO:Mn (5wt%) nanorods at 10K."
