Abstract
Section titled “Abstract”Nitrogen-vacancy (<a:math xmlns:a=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><a:mrow><a:mrow><a:mi mathvariant=“normal”>N</a:mi></a:mrow></a:mrow></a:math>-<e:math xmlns:e=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><e:mi>V</e:mi></e:math>) centers in diamond enable nuclear magnetic resonance (NMR) spectroscopy of samples at the nano- and microscale. However, at typical tesla-scale NMR magnetic field strengths, <h:math xmlns:h=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><h:mrow><h:mrow><h:mi mathvariant=“normal”>N</h:mi></h:mrow></h:mrow></h:math>-<l:math xmlns:l=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><l:mi>V</l:mi></l:math>-NMR protocols become difficult to implement due to the challenge of driving fast <o:math xmlns:o=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><o:mrow><o:mrow><o:mi mathvariant=“normal”>N</o:mi></o:mrow></o:mrow></o:math>-<s:math xmlns:s=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><s:mi>V</s:mi></s:math> pulse sequences sensitive to nuclear Larmor frequencies above a few megahertz. We perform simulations and theoretical analysis of the experimental viability of <v:math xmlns:v=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><v:mrow><v:mrow><v:mi mathvariant=“normal”>N</v:mi></v:mrow></v:mrow></v:math>-<z:math xmlns:z=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><z:mi>V</z:mi></z:math> NMR at tesla-scale magnetic fields using a measurement protocol called DRACAERIS (Double Rewound ACquisition Amplitude Encoded Radio Induced Signal). DRACAERIS detects the longitudinal magnetization of the NMR sample at a much lower driven Rabi frequency, more suitable technically for <cb:math xmlns:cb=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><cb:mrow><cb:mrow><cb:mi mathvariant=“normal”>N</cb:mi></cb:mrow></cb:mrow></cb:math>-<gb:math xmlns:gb=“http://www.w3.org/1998/Math/MathML” display=“inline” overflow=“scroll”><gb:mi>V</gb:mi></gb:math> detection. We discuss how pulse errors, finite pulse lengths, and nuclear spin-spin couplings affect the resulting NMR spectra. We find that DRACAERIS is less susceptible to pulse imperfections and off-resonance effects than previous protocols for longitudinal magnetization detection. We also identify reasonable parameters for experimental implementation. Published by the American Physical Society 2024
