A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

High-precision magnetometers are used to measure the strength and direction of magnetic fields for various applications. However, many of today's magnetometers must operate at extremely low ...

The researchers fabricated chip-based interferometers (pictured) to measure how light propagating through a magneto-optic material changed in response to a magnetic field. WASHINGTON — Researchers ...

An international team of researchers led by Lancaster University has discovered a highly efficient mechanism for shaking magnets using very short light pulses, shorter than a trillionth of a second.

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in sensitivity ...

Steering nanobots in crowded biological environments raises questions about the limits on the size of a steerable propeller under thermal noise. Here, the authors theoretically investigate ...

Abstract: This article proposes a new method to calibrate the B–H properties measured by the vibrating sample magnetometer (VSM) for bar-shaped samples. It compensates for finite size and ...

Abstract: Array-form ultrahigh sensitivity single-beam atomic magnetometers are ideal for high-resolution biomagnetic imaging applications, such as magnetocardiography and magnetoence-phalography. In ...
