    The combination of a 60 T pulsed-field magnet and the continuous tunability of a high power, picosecond free-electron laser provides a powerful facility to study, e.g. cyclotron resonance . Electron paramagnetic resonance (EPR) = Electron spin resonance (ESR) spectroscopy Same underlying physical principles as in nuclear magnetic resonance (NMR) One unpaired (free) electron: Zeeman effect: ∆𝑈=𝑔 𝑒 𝑔= ℎ𝜈 𝑒 (resonance condition) g: g factor for free electron: g e = b e: Bohr magneton.

    The Table of Contents for the book is as follows: * Resonant Polaron Effect of Shallow Indium Donors in CdTe * Magnetic Resonance of Dopants and Defects in GaN-Based Materials and Devices * Some Aspects of the Hydrogen-Dopant Interactions in Compound Semiconductors * Shallow Electronic Traps Associated with Hydrogen Complexes in Crystalline Silicon * Author: C. A. J. Ammerlaan, B. Pajot.   EMR stands for electron magnetic resonance. EMR is very similar to the two other resonance techniques that take place here at the lab: nuclear magnetic resonance (NMR) and ion cyclotron resonance (ICR). The big difference is that EMR looks at electrons rather than nuclei (which is the case in NMR).

    The pulsed high-magnetic-field facility is the first major science and technology infrastructure project that will be built by the Huazhong University of Science and Technology under the direct leadership of the Ministry of Education as part of the National Key Science and Technology Basic Establishment Project for high magnetic field.

At T this is nm and [43], leading to the first experiments with far infrared resonance [92]. In Western Europe, pulsed-field laboratories were established.

Principles of Pulse Electron Paramagnetic Resonance 1st Edition as a guide-book in this rapidly developing field of science. But this book will be extremely useful not only for beginners. Even experienced practitioners in the filed will gain a fresh look from the high-level experts at the opportunities for new applications and further Cited by:   Magnetic Excitations in Random Systems in High Magnetic Fields Far Infrared Paramagnetic Resonances in Dyal Garnet Ferromagnetic Resonance in 3d Metals at High Magnetic Fields on the EPR of 3d4 and 3d6 Ions at High Magnetic Fields Submillimeter Wave ESR of CsFeCl3 in a Pulsed High Magnetic Field Chapter 9.

SemiconductorsBook Edition: 1. A free-electron laser is used to power a pulsed electron paramagnetic resonance spectrometer at GHz, demonstrating a range of experimental possibilities such as the manipulation of spin-1/2.

Here we present results from a pulsed EPR spectrometer powered by a free-electron laser (FEL). The spectrometer operates at T ( GHz), and can be powered either by a mW, GHz solid-state source or by UCSB’s millimetre-wave FEL (mm-FEL), with a maximum power of 1 kW.

The use of molecular gas lasers in the far-IR and IR ranges, as well as YAG and He-Ne lasers in the near-IR range, has led to the discovery of novel phenomena that are typical of extremely high magnetic fields (in the megagauss range) in semiconductors, semimetals, and magnetic Author: N.

Pulsed high-field / high-frequency EPR offers the possibility to detect coherences and relaxation properties in disordered samples in much detail. The reason is the spectrally resolved G-tensor, which allows to obtain orientation dependent information even in Cited by: 9.

High-field/high frequency EPR spectroscopy measurements are shown. Experiments were carried out at and GHz frequencies. The employed apparatus uses a novel combination of far infrared molecular lasers and of probehead exploiting dielectric resonators working in the whispering gallery modes.

The free electron laser Free electron Laser for Advanced spectroscopy and high Resolution Experiments (FLARE) at the FELIX Laboratory generates powerful radiation in the frequency range of –3 THz.

The performance of the THz spectrometer is measured via high-field electron spin resonance (ESR) in the paramagnetic benchmark system 2,2-diphenylpicrylhydrazyl (DPPH).

Pulse EPR (electron paramagnetic resonance) is one of the newest and most widely used techniques for examining the structure, function and dynamics of biological systems and synthetic materials. Until now, however, there has been no single text dedicated to this growing area of research. This text addresses the need for a comprehensive overview of Pulse EPR.

ESR = Electron Spin Resonance = EPR = Electron Paramagnetic Resonance = EMR = Electron Magnetic Resonance. Electromagnetic sources are the bottleneck in the development of high-power pulsed EPR at high magnetic fields. Most high-power pulsed EPR spectrometers in the world operate at T (f Larmor= GHz) or T (f Larmor=34 GHz) and are powered by vacuum electronic devices called traveling wave tube amplifiers [19].

This book provides an introduction to the underlying theory, fundamentals, and applications of EPR spectroscopy, as well as new developments in the area.

Knowledge of the topics presented will allow the reader to interpret of a wide range of EPR spectra, as well as help them to apply EPR techniques to problem solving in a wide range of areas: organic, inorganic. Static magnetic fields result from either fixed magnets or the magnetic flux resulting from the flow of direct current (DC).

Sources producing these fields include (but are not limited to) the following: Nuclear Magnetic Resonance (NMR) imaging and spectroscopy devices; Electron Paramagnetic Resonance (EPR, ESR, EMR) devices.Electron paramagnetic resonance (EPR), also called electron-spin resonance (ESR), selective absorption of weak radio-frequency electromagnetic radiation (in the microwave region) by unpaired electrons in the atomic structure of certain materials that simultaneously are subjected to a constant, strong magnetic unpaired electrons, because of their spin, behave like .
