An approach to the selective observation of paramagnetic centers in thin samples or surfaces with electron spin resonance (ESR) is presented. The methodology is based on the use of a surface microresonator that enables the selective obtention of ESR data from thin layers with minimal background signals from the supporting substrate. An experimental example is provided, which measures the ESR signal from a 1.2 µm polycrystalline silicon layer on a glass substrate used in modern solar-cell…

Superconducting micro-resonators for electron spin resonance - the good, the bad, and the future.
The design, fabrication, and testing results of surface micro-resonators made of yttrium barium copper oxide (YBCO), a superconducting material that operates also at high magnetic fields and makes it possible to pursue ESR at moderate cryogenic temperatures, are presented.
Recent trends in high spin sensitivity magnetic resonance.
The conclusion from this comparison is that induction detection is still indispensable, and as such, it is very important to look for ways to significantly improve it.


Cryogenic electron spin resonance microimaging probe.
Experimental results demonstrate the system's capability to acquire two - as well as three-dimensional images with a flat test sample of phosphorus-doped silicon, and verify the resonator's resonance mode - they show its B(1) distribution, which makes it possible to estimate the number of spins measured in the sample.
Electronic spin detection in molecules using scanning-tunneling- microscopy-assisted electron-spin resonance
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
Scaling of sensitivity and efficiency in planar microresonators for electron spin resonance.
A series of planar microresonators are described that show large improvements over conventional ESR resonators in terms of microwave conversion efficiency (microwave field strength for a given input power) and sensitivity (minimum number of detectable spins).
Note: High sensitivity pulsed electron spin resonance spectroscopy with induction detection.
Through the use of a new type of surface loop-gap microresonators (inner size of 20 μm), operating at cryogenic temperatures at a field of 0.5 T, one can improve upon this sensitivity barrier by more than 2 orders of magnitude and reach spin sensitivities of ~1.5 × 10(6) spins/√Hz or ~2.5× 10(4) spins for 1 h.
Scanned-probe detection of electron spin resonance from a nitroxide spin probe
An approach that extends the applicability of ultrasensitive force-gradient detection of magnetic resonance to samples with spin-lattice relaxation times (T 1) as short as a single cantilever period is reported, suggesting that it is well suited to push magnetic resonance detection and imaging of nitroxide spin labels in an individual macromolecule to single-spin sensitivity.
