Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in a n
Synchrotron-based X-ray spectroscopy is a powerful tool to study element-specific magnetism. Here, X-ray detected paramagnetic resonance on molecular quantum bit candidates is demonstrated, paving the way toward the element-specific detection of coherently excited spin superposition states. Andrin Doll ...
