Title: Multi-frequency force-detected electron spin resonance in the millimeter-wave region up to 150 GHz

Abstract

In this article, a novel technique is developed for multi-frequency force-detected electron spin resonance (ESR) in the millimeter-wave region. We constructed a compact ESR probehead, in which the cantilever bending is sensitively detected by a fiber-optic Fabry-Perot interferometer. With this setup, ESR absorption of diphenyl-picrylhydrazyl radical (<1 μg) was clearly observed at multiple frequencies of up to 150 GHz. We also observed the hyperfine splitting of low-concentration Mn{sup 2+} impurities(∼0.2%) in MgO.

  • The electron spin echo detected ESR spectrum of 1-ethylbutyl radicals in a ..gamma..-irradiated n-hexane single crystal was measured at 77 K as a function of the time of the longitudinal relaxation, t/sub 1/. The longitudinal relaxation was caused by the spectral diffusion induced by the modulation of isotropic hyperfine coupling constants, so that the relaxation rate did not depend on the direction of the crystal with respect to the static magnetic field. Analysis of the thermal motion of the radical in the crystal revealed that the slow twisting motion of the C-C bond induces the modulation of mainly isotropic ..beta..-protonmore » hyperfine coupling constants. The resolution of the ESE-detected ESR spectrum increased with increasing t/sub 1/. The observed spectra compared well with the t/sub 1/-dependent ESR spectra calculated by utilizing a spectral diffusion model in which the spectral shape of each hyperfine line at t/sub 1/ = 0 is equivalent to the distribution of the diffusion time in the spectral space.« less

  • We describe instrumentation for a high-frequency electron paramagnetic resonance (EPR) and pulsed electron-electron double resonance (PELDOR) spectroscopy. The instrumentation is operated in the frequency range of 107−120 GHz and 215−240 GHz and in the magnetic field range of 0−12.1 T. The spectrometer consisting of a high-frequency high-power solid-state source, a quasioptical system, a phase-sensitive detection system, a cryogenic-free superconducting magnet, and a {sup 4}He cryostat enables multi-frequency continuous-wave EPR spectroscopy as well as pulsed EPR measurements with a few hundred nanosecond pulses. Here we discuss the details of the design and the pulsed EPR sensitivity of the instrumentation. We also presentmore » performance of the instrumentation in unique experiments including PELDOR spectroscopy to probe correlations in an insulating electronic spin system and application of dynamical decoupling techniques to extend spin coherence of electron spins in an insulating solid-state system.« less
  • The observation of coherent dimers in their excited triplet state is reported for a molecular crystal of 1,2,4,5-tetrachlorobenzene at low temperatures (below 4.2 K). Utilizing the theory developed in a previous paper, the coherence time (10/sup -6/ sec) and the anisotropy of the resonance interactions in the excited state were established. The identification of the dimer as translationally equivalent, from the zero-field optically detected magnetic-resonance spectra, establishes the effective dispersion for the triplet exciton band of the neat crystal. Moreover, the magnitude of the resonance transfer time was shown to be much less than the coherence time: the dimer ismore » coherent for a period of 10/sup 5/ times that associated with the stochastic limit.

  • We present experimental results on measuring the emittance of short-pulsed (≤100 μs) high-current (80–100 mA) ion beams of heavy gases (Nitrogen, Argon) formed from a dense plasma of an ECR source of multiply charged ions (MCI) with quasi-gas-dynamic mode of plasma confinement in a magnetic trap of simple mirror configuration. The discharge was created by a high-power (90 kW) pulsed radiation of a 37.5-GHz gyrotron. The normalized emittance of generated ion beams of 100 mA current was (1.2–1.3) π mm mrad (70% of ions in the beams). Comparing these results with those obtained using a cusp magnetic trap, it was concluded thatmore » the structure of the trap magnetic field lines does not exert a decisive influence on the emittance of ion beams in the gas-dynamic ECR source of MCI.« less
