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 ...

Fiber optic sensor measures tiny magnetic fields

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an alternative to the magnetic ...

Neutrons help demystify multiferroic materials

Materials used in electronic devices are typically chosen because they possess either special magnetic or special electrical properties. However, an international team of researchers using neutron scattering recently identified ...

THEMIS sees Auroras move to the rhythm of Earth's magnetic field

The majestic auroras have captivated humans for thousands of years, but their nature—the fact that the lights are electromagnetic and respond to solar activity—was only realized in the last 150 years. Thanks to coordinated ...
