This book brings together the three branches of magnetic resonance spectroscopy namely, electron spin resonance (ESR), nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) and presents a coherent and progressive coverage Author: D.N. Sathyanarayana.   The Friedel approach is used to theoretically describe the anomalies of spin magnetic susceptibility that are caused by the resonance scattering of conduction electrons by impurities in metals and doped semiconductors. The localization of the electron density under resonance conditions is shown to result in the temperature dependence of the susceptibility that is described by the Curie Cited by: 1.

Abstract The recent electron magnetic resonance studies (EMR) studies [Decker, Phys. Rev. B 66, ()] of Fe 3+ ions in BaTiO 3 indicate a pronounced discrepancy concerning the values of the fourth-rank zero-field splitting (ZFS) parameters from various authors. Our reanalysis of the ZFS terms for the pertinent symmetry cases reveals a misinterpretation of the ZFS parameters by Decker. species constitute an inevitable part of the electronic devices’ industry and greatly affect their performance (1). Traditionally, the identification and study of these species are carried out using electron spin resonance (ESR). For example, in the case of point defects and impurities.

The Handbook includes key contributions from leading scientists and provides over tables and figures. Although specific ESR subfields are covered in numerous books and journals, the Handbook of Electron Spin Resonance is the only comprehensive reference to present extensive tabulation of data and experimental results.5/5(1).

In this chapter, we will focus on the study by EPR of point defects in semiconductor materials. Indeed, impurities, vacancies, anti -sites and complexes of them, in a diamagnetic material, may exhibit a local electronic reconstruction favoring unpaired electrons, and consequently, such defects have a nonzero electon spin.

Of course, point defects may exist in an S = 0 state and then be EPR silent. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry.

Abstract: A promising platform for quantum information processing is that of silicon impurities, where the quantum states are manipulated by magnetic resonance. Such systems, in abstraction, can be considered as a nucleus of arbitrary spin coupled to an electron of spin one-half via an isotropic hyperfine : M.

The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei.

EPR spectroscopy is particularly useful for studying metal complexes or organic radicals.
