WASHINGTON -- 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 ...

Crystals doped with rare-earth (RE) ions exhibit very narrow linewidths of the optical transitions. The narrow-line spectra of triply ionized RE elements cover the entire visible and infrared range.

This file type includes high resolution graphics and schematics when applicable. The latest generation of 3D magnetic position sensors from ams AG uses a pair of sensor elements (pixels) that make it ...

A new Israeli study suggests that light can directly influence materials in a magnetic field in ways scientists had long overlooked, a finding that could affect technologies from fiber-optic ...

Detection of vector magnetic fields at nanoscale dimensions is an outstanding problem in fields ranging from fundamental physics and material sciences to practical applications in biological imaging ...
