Researchers from the KIT Center for Functional Nanostructures (CFN) and the Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS) have created the world's smallest magnetic field sensor using Spin electronics and molecular electronics. The whole sensor is just one single organic molecule (H2-phthalocyanin that is also used as blue dye in ball pens).
