Magnetic Microscopy of Skyrmions in Magnetic Thin Films with Chiral Overlayers
Buddhika Hondamuni, Théo Balland, Fabian Kammerbauer +15
Topologically nontrivial magnetic textures such as skyrmions offer promising opportunities for spintronic applications. In recent years, it has been shown that the magnetic propert…
Microwave-free vector magnetometry and crystal orientation determination with Nitrogen-Vacancy centers using Bayesian inference
Hilario Espinós, Omkar Dhungel, Arne Wickenbrock +3
Nitrogen-vacancy (NV) centers in diamond provide a solid-state platform for quantum sensing. While optically detected magnetic resonance techniques offer high sensitivity, their re…
Low-field all-optical detection of superconductivity using NV nanodiamonds
Omkar Dhungel, Saravanan Sengottuvel, Mariusz Mrozek +5
Nitrogen-vacancy centers in nanodiamond offer a microwave-free, noninvasive platform for probing superconductors via near zero-field cross-relaxation magnetometry. We demonstrate t…
Microwave-free imaging magnetometry with nitrogen-vacancy centers in nanodiamonds at near-zero field
Saravanan Sengottuvel, Omkar Dhungel, Mariusz Mrózek +4
Magnetometry using Nitrogen-Vacancy (NV) color centers in diamond predominantly relies on microwave spectroscopy. However, microwaves may hinder certain studies involving biologica…
Near-zero-field microwave-free magnetometry with nitrogen-vacancy centers in nanodiamonds
Omkar Dhungel, Mariusz Mrózek, Till Lenz +6
We study the fluorescence of nanodiamond ensembles as a function of static external magnetic field and observe characteristic dip features close to the zero field with potential fo…
Microwave-free wide-field magnetometry using nitrogen-vacancy centers
Joseph Shaji Rebeirro, Muhib Omar, Till Lenz +4
A wide-field magnetometer utilizing nitrogen-vacancy (NV) centers in diamond that does not require microwaves is demonstrated. It is designed for applications where microwaves need…
