By combining the spatial resolution of a scanning-tunneling microscope (STM) with the electronic spin sensitivity of electron-spin resonance, it is possible to detect the presence of localized spins on surfaces as mentioned in this paper.Abstract:
By combining the spatial resolution of a scanning-tunneling microscope (STM) with the electronic spin sensitivity of electron-spin resonance, we show that it is possible to detect the presence of localized spins on surfaces The principle is that a STM is operated in a magnetic field, and the resulting component of the tunnel current at the Larmor (precession) frequency is measured This component is nonzero whenever there is tunneling into or out of a paramagnetic entity We have succeeded in obtaining spectra from free radical molecules from which the g factor of a spin entity may be inferred For the molecules studied here, α,γ-bisdiphenylene-β-phenylallyl, g was found to be 2±01read more

Single spin detection by magnetic resonance force microscopy
TL;DR: The long relaxation time of the measured signal suggests that the state of an individual spin can be monitored for extended periods of time, even while subjected to a complex set of manipulations that are part of the MRFM measurement protocol.

TL;DR: The road is now open to address individual molecules wired to a conducting surface in their blocked magnetization state, thereby enabling investigation of the elementary interactions between electron transport and magnetism degrees of freedom at the molecular scale.

Theories of scanning probe microscopes at the atomic scale
TL;DR: In this article, the authors discuss and compare the present status of computational modeling of two of the most popular SPM methods (scanning tunneling microscopy and scanning force microscopy) in conjunction with their applications to studies of surface structure and properties with atomic resolution.

Atomic force microscope
TL;DR: The atomic force microscope as mentioned in this paper is a combination of the principles of the scanning tunneling microscope and the stylus profilometer, which was proposed as a method to measure forces as small as 10-18 N. As one application for this concept, they introduce a new type of microscope capable of investigating surfaces of insulators on an atomic scale.

Direct observation of the precession of individual paramagnetic spins on oxidized silicon surfaces
TL;DR: In this paper, the spin precession in a constant magnetic field induces a modulation in the tunneling current at the Larmor frequency, which is localized over distances less than 10 A/r{} and follows the expected magnetic field dependence.

TL;DR: In this paper, the authors investigated individual nitrogen-vacancy defect centers by low-temperature confocal microscopy and fluorescence excitation spectroscopy and found that at temperatures below 90 K the fluorescence intensity of individual centers drastically diminishes because of the population of a metastable singlet state in near resonance with the optically excited state.
