Electron Spin Resonance spectroscopy with femtoliter detection volume [PDF]
Applied Physics Letters, 2020 We report electron spin resonance measurements of donors in silicon at millikelvin temperatures using a superconducting $LC$ planar micro-resonator and a Josephson Parametric Amplifier. The resonator includes a nanowire inductor, defining a femtoliter detection volume.

The effect of spin polarization on double electron–electron resonance (DEER) spectroscopy [PDF]
Magnetic Resonance, 2022 Double electron–electron resonance (DEER) spectroscopy measures the distribution of distances between two electron spins in the nanometer range, often on doubly spin-labeled proteins, via the modulation of a refocused spin echo by the dipolar interaction

Spin Resonance Spectroscopy with an Electron Microscope [PDF]
Quantum Sci. Technol. 9, 035051 (2024)Coherent spin resonance methods, such as nuclear magnetic resonance and electron spin resonance spectroscopy, have led to spectrally highly sensitive, non-invasive quantum imaging techniques. Here, we propose a pump-probe spin resonance spectroscopy approach, designed for electron microscopy, based on microwave pump fields and electron probes.

Pulsed electron spin resonance spectroscopy in the Purcell regime. [PDF]
Journal of Magnetic Resonance, 2019 When spin relaxation is governed by spontaneous emission of a photon into the resonator used for signal detection (the Purcell effect), the relaxation time $T_1$ depends on the spin-resonator frequency detuning $ $ and coupling constant $g$. We analyze the consequences of this unusual dependence for the amplitude and temporal shape of a spin-echo in a

Myocardial ischemia and reperfusion: direct evidence for free radical generation by electron spin resonance spectroscopy. [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1988 Electron spin resonance spectroscopy has recently been used by others to detect directly radical species in isolated perfused hearts. Sample processing prior to spectroscopy in this study involved pulverization of tissue, which can artifactually generate

Electron spin resonance spectroscopy of small ensemble paramagnetic spins using a single nitrogen-vacancy center in diamond [PDF]
J. Appl. Phys. 120, 123907 (2016), 2015 A nitrogen-vacancy (NV) center in diamond is a promising sensor for nanoscale magnetic sensing. Here we report electron spin resonance (ESR) spectroscopy using a single NV center in diamond. First, using a 230 GHz ESR spectrometer, we performed ensemble ESR of a type-Ib sample crystal and identified a substitutional single nitrogen impurity as a major ...

Development of planar microstrip resonators for electron spin resonance spectroscopy [PDF]
Eur. Phys. J. Appl. Phys. 90, 31001 (2020), 2020 This work focuses on the development of planar microwave resonators which are to be used in electron spin resonance spectroscopic studies. Two half wavelength microstrip resonators of different geometrical shapes, namely straight ribbon and omega, are fabricated on commercially available copper clad microwave laminates.
