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.  […]

Peer into the Future of Magnetics for Energy at ARPA-E Summit 

April 4, 2022 Editorial Staff Comments Off on Peer into the Future of Magnetics for Energy at ARPA-E Summit 

Magnetics technology plays a key role in much of today’s energy research – looking for breakthroughs in electric propulsion for aviation, high-temperature superconductors, fusion energy, machine modeling for power magnetics, new embedded cooling and winding topologies for improving permanent-magnet motors, even magnetic resonance imaging of crop roots. Visitors to the U.S. Department of Energy’s ARPA-E Energy Innovation Summit & Technology Showcase can explore a fascinating array of these and meet the scientists behind them, as well as many other aspects of energy R&D. It will be held in Denver in May. This article highlights some of the magnetic-related projects. […]
