Researchers Develop Superparamagnetic Gold Nanoshells

A solution-phase process has been developed by CNM users from the University of California at Riverside, working collaboratively with the Nanophotonics Group at the Argonne National Laboratory, for synthesizing stable multifunctional colloidal particles composed of a superparamagnetic Fe3O4 core, a gold nanoshell, and a mesoporous silica outer layer.

New Spintronics Finding can Lead to Further Development of Nanoscale Magnetic Storage Devices

Though scientists argue that the emerging technology of spintronics may trump conventional electronics for building the next generation of faster, smaller, more efficient computers and high-tech devices, no one has actually seen the spin—a quantum mechanical property of electrons—in individual atoms until now.

Photoemission Experiments Shed Light on Origin of Enigmatic Type of Magnetism in Iron

Iron is the most useful magnet in our daily life. It is a 'ferromagnet' at room temperature and ambient pressure, but displays a variety of other magnetic properties that depend on its crystallographic structure....

Researchers Study Feasibility of Magnetically-Guided Nanoparticles for Delivering Drugs

Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.

New Material Mimics Magnetic Monopole

Researchers from Imperial College London have created a structure that acts like a single pole of a magnet, a feat that has evaded scientists for decades. The researchers say their new Nature Physics study takes them a step closer to isolating a 'magnetic monopole.'
