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. […]

Technique Tunes into Graphene Nanoribbons’ Electronic Potential

May 5, 2022 Guest Blog Comments Off on Technique Tunes into Graphene Nanoribbons’ Electronic Potential

Ever since graphene, a thin carbon sheet just one-atom thick, was discovered more than 15 years ago, the wonder material became a workhorse in materials science research. From this body of work, other researchers learned that slicing graphene along the edge of its honeycomb lattice creates one-dimensional zigzag graphene strips or nanoribbons with exotic magnetic properties […]
