Scientists have used a blue laser and an enhanced optical technique to detect the elusive optical Hall effect in everyday metals like copper and gold, revealing hidden magnetic behaviors and opening new avenues in spin physics, quantum tech, and electronics without extreme conditions or wires.
Scientists have developed a new laser-based method to detect subtle magnetic effects in common metals like copper, gold, and aluminum, revealing hidden magnetic signals and opening new avenues for advancements in electronics and quantum technologies.
Researchers at the National Institute of Standards and Technology (NIST) are developing a thermometry system called Thermal MagIC that uses nano-sized spheres embedded in objects to measure temperature. The magnetic signals produced by these spheres correspond to specific temperatures, allowing for high spatial resolution temperature imaging. In a recent study, the researchers characterized the temperature sensitivity and spatial resolution of their imaging system, bringing them closer to creating a reliable "thermometry camera." The next step is to measure temperature gradients, which would enable true temperature imaging.
