Creation of High-Density Nitrogen-Vacancy Centers in CVD Diamond using High-Energy Photons from Ar+ Plasma

https://doi.org/10.1364/CLEO_AT.2024.JW2A.92

Karki, Prem Bahadur; Timalsina, Rupak; Dowran, Mohammadjavad; Aregbesola, Ayodimeji E; Laraoui, Abdelghani; Ambal, Kapildeb (January 2024, Optica Publishing Group)

We use high-energy photons generated from Ar⁺plasma source to create a high-density and thick ( up to a thickness of 150 µm) nitrogen-vacancy centers layer in a commercially available type-IIa CVD-grown diamond substrate.

Opportunities for nitrogen-vacancy-assisted magnetometry to study magnetism in 2D van der Waals magnets

https://doi.org/10.1063/5.0091931

Laraoui, Abdelghani; Ambal, Kapildeb (August 2022, Applied Physics Letters)

Exploring and understanding magnetism in two-dimensional (2D) van der Waals (vdW) magnetic materials present a promising route for developing high-speed and low-power spintronics devices. Studying their magnetic properties at the nanoscale is challenging due to their low magnetic moment compared to bulk materials and the requirements of highly sensitive magnetic microscopy tools that work over a wide range of experimental conditions (e.g., temperature, magnetic field, and sample geometry). This Perspective reviews the applications of nitrogen-vacancy center (NV) based magnetometry to study magnetism in 2D vdW magnets. The topics discussed include the basics, advantages, challenges, and the usage of NV magnetometry.
