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…
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…
Near zero-field microwave-free magnetometry with ensembles of nitrogen-vacancy centers in diamond
Omkar Dhungel, Till Lenz, Muhib Omar +8
We study cross-relaxation features near zero magnetic field with ensembles of nitrogen-vacancy (NV) centers in diamond and examine their properties in samples with a range (0.9 ppm…
Probing topological spin structures using light-polarization and magnetic microscopy
Till Lenz, Georgios Chatzidrosos, Zhiyuan Wang +12
We present an imaging modality that enables detection of magnetic moments and their resulting stray magnetic fields. We use wide-field magnetic imaging that employs a diamond-based…
Magnetic sensing at zero field with a single nitrogen-vacancy center
Till Lenz, Arne Wickenbrock, Fedor Jelezko +2
Single nitrogen-vacancy (NV) centers are widely used as nanoscale sensors for magnetic and electric fields, strain and temperature. Nanoscale magnetometry using NV centers allows f…
Zero-field magnetometry based on nitrogen-vacancy ensembles in diamond
Huijie Zheng, Jingyan Xu, Geoffrey Iwata +10
Ensembles of nitrogen-vacancy (NV) centers in diamonds are widely utilized for magnetometry, magnetic-field imaging and magnetic-resonance detection. They have not been used for ma…
Color centers in diamond as novel probes of superconductivity
Victor M. Acosta, Louis S. Bouchard, Dmitry Budker +6
Magnetic imaging using color centers in diamond through both scanning and wide-field methods offers a combination of unique capabilities for studying superconductivity, for example…
Widefield imaging of superconductor vortices with electron spins in diamond
Yechezkel Schlussel, Till Lenz, Dominik Rohner +11
Understanding the mechanisms behind high- Type-II superconductors (SC) is still an open task in condensed matter physics. One way to gain further insight into the microscopi…
