Research Conducted at University of Alberta Has Updated Our Knowledge about Nanotechnology

June 24, 2014

By a News Reporter-Staff News Editor at Physics Week -- Investigators discuss new findings in Nanotechnology. According to news originating from Edmonton, Canada, by VerticalNews correspondents, research stated, "Strong magnetoresistance effects are often observed in ferromagnet-nonmagnet multilayers, which are exploited in state-of-the-art magnetic field sensing and data storage technologies. In this work we report a novel current-perpendicular-to-plane magnetoresistance effect in multilayer graphene as grown on a catalytic nickel surface by chemical vapor deposition."

Our news journalists obtained a quote from the research from the University of Alberta, "A negative magnetoresistance effect of similar to 10(4)% has been observed, which persists even at room temperature. This effect is correlated with the shape of the 2D peak as well as with the occurrence of D peak in the Raman spectrum of the as-grown multilayer graphene."

According to the news editors, the research concluded: "The observed magnetoresistance is extremely high as compared to other known materials systems for similar temperature and field range and can be qualitatively explained within the framework of 'interlayer magnetoresistance' (ILMR)."
