"spin" via the electrons in the same atom through the needle of a scanning tunneling microscope.
To their surprise, the spin remained stable for several seconds, offering prospects for enhanced control of the magnetic nucleus. The research, published in Nature Communications, is a step forward for quantum sensing at the atomic scale.
A scanning tunneling microscope (STM) consists of an atomically sharp needle that can "feel" single atoms on a surface and make images with atomic resolution.
