Urban Magnetic Fields Reveal Clues about Energy Efficiency, Pollution

In Journal of Applied Physics, researchers from the United States and Germany present a comparative analysis of urban magnetic fields between two U.S. cities: Berkeley, California, and the Brooklyn borough of New York City. They explore what kinds of information can be extracted using data from magnetic field sensors to understand the working of cities and provide insights that may be crucial for preventative studies.

Coupled magnetic materials show interesting properties for quantum applications

In a new study led by the U.S. Department of Energy’s Argonne National Laboratory, researchers have uncovered a novel way in which the excitations of magnetic spins in two different thin films can be strongly coupled to each other through their common interface.

A joint venture at the nanoscale

Scientists at Argonne National Laboratory report fabricating and testing a superconducting nanowire device applicable to high-speed photon counting. This pivotal invention will allow nuclear physics experiments that were previously thought impossible.
