The detection of faint magnetic fields from single-electron and nuclear spins at the atomic
scale is a long-standing challenge in physics. While current mobile quantum sensors …

We combined the high-energy resolution of conventional spin resonance (here~ 10 nano–
electron volts) with scanning tunneling microscopy to measure electron paramagnetic …

Vacuum tunneling of spin-polarized electrons from a ferromagnetic CrO 2 tip into a Cr (001)
single crystal has been observed by means of a scanning tunneling microscope (STM) …

In recent years inelastic spin-flip spectroscopy using a low-temperature scanning tunneling
microscope has been a very successful tool for studying not only individual spins but also …

The latest concepts for quantum computing and data storage rely on the addressing and
manipulation of single spins. A limitation for single atoms or molecules in contact with a …

We report on the magnetic properties of individual Fe atoms deposited on MgO (100) thin
films probed by x-ray magnetic circular dichroism and scanning tunneling spectroscopy. We …

Local spins coupled to superconductors give rise to several emerging phenomena directly
linked to the competition between Cooper pair formation and magnetic exchange. These …

We demonstrate using inelastic scanning tunneling spectroscopy and simulations based on
density functional theory that the amplitude and sign of the magnetic anisotropy energy for a …

High–energy resolution spectroscopic studies of quantum magnets proved extremely
valuable in accessing magnetodynamics quantities, such as energy barriers, magnetic …
