Quantum Scale Sensors used to Measure Planetary Scale Magnetic Fields

May 19, 2025 Editorial Staff 0

Magnetic fields are everywhere in our solar system. They originate from the Sun, planets, and moons, and are carried throughout interplanetary space by solar wind. This is precisely why magnetometers—devices used to measure magnetic fields—are flown on almost all missions in space to benefit the Earth, Planetary, and Heliophysics science communities, and ultimately enrich knowledge for all humankind.

Magnetic Imaging with SQUID sensitivity by Quantum Design, and New CEO 

February 19, 2025 Editorial Staff Comments Off on Magnetic Imaging with SQUID sensitivity by Quantum Design, and New CEO 

The QDM.IO is the first system on the market which provides large area imaging of the magnetic field distribution using measurement based on nitrogen-vacancy centers implanted in a diamond. Conventional NV center-based microscopes use a single NV center in the tip and scan the sample, however, the heart of this microscope is a chip with many NV centers which can measure a large area simultaneously. The result is nanotesla sensitivity that not only detects the strength but also the local vector of the magnetic field.  […]

Ultraminiature Magnetometer Rotation & Proximity Sensing from NVE 

October 23, 2024 Editorial Staff Comments Off on Ultraminiature Magnetometer Rotation & Proximity Sensing from NVE 

Tunneling magnetoresistance analog magnetic sensors are revolutionizing sensing capability for product developers. Two new ultraminiature TMR devices from NVE can sense rotation and proximetry with unprecedented precision. One is a dual-axis sensor for sensitive rotation sensing, the other a proximetry sensor that can detect smaller objects at greater distances with more precision than ever before. They expand NVE’s line of ALT-Series TMR analog magnetometers. […]
