Magnetoresistance ratio enhancement in Heusler-based alloy

Magnetic field sensors can enhance applications that require efficient electric energy management. Improving magnetic field sensors below the picoTesla range could enable a technique to measure brain activity at room temperature ...

Discovery furthers understanding of superconductivity

(Phys.org) —Physicists at the University of Arkansas have collaborated with scientists in the United States and Asia to discover that a crucial ingredient of high-temperature superconductivity could be found in an entirely ...

The first controllable atom SQUID

(Phys.org)—Scientists have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular quantum state of the ...

Mini-sensor measures magnetic activity in human brain

A miniature atom-based magnetic sensor developed by the National Institute of Standards and Technology (NIST) has passed an important research milestone by successfully measuring human brain activity. Experiments reported ...

Researchers create light from 'almost nothing'

(PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced ...

Researchers synthesize carbon nanosolenoid with Riemann surfaces

Albert Einstein constructed equations of general relativity by adopting Riemann geometry. In addition to the key role it played in mathematics and physics, Riemann geometry has provided predictions for the properties of curved ...
