Researchers from George Washington University Report on Findings in Nanostructures

June 27, 2014



By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nanostructures are discussed in a new report. According to news originating from Washington, District of Columbia, by NewsRx editors, the research stated, "The magnetic properties and propagation of electromagnetic waves in magnetic nanoparticle systems strongly depend on the interactions between the nanosize elements having finite separation. Several aspects of the role of the dipolar and exchange interactions are reviewed on model periodic 2D and 3D magnetic nanostructures."

Our news journalists obtained a quote from the research from George Washington University, "Experiments and theory expose the critical role of proper calculation of dipole fields and statistical distributions. The control and optimization of interactions is illustrated on an example of hexagonal Permalloy ellipse arrays. The competing particle and array anisotropy, leading to a spin reorientation phase transition in Permalloy nanowires, is demonstrated."

According to the news editors, the research concluded: "Finally, the effect of the system configuration on the interactions with electromagnetic waves is shown for ferrite and metal magnetic nanosphere arrays, demonstrating specific nanomagnetic effects, as a transition from insulator to metal, and early onset of nonlinearities."
