Superconductivity and magnetism in RbxFe2-ySe2: Impact of thermal treatment on mesoscopic phase separation [PDF]
, 2012 An extended study of the superconducting and normal-state properties of various as-grown and post-annealed RbxFe2-ySe2 single crystals is presented. Magnetization experiments evidence that annealing of RbxFe2-ySe2 at 413 K, well below the onset of phase ...

The influence of the long-lived quantum Hall potential on the characteristics of quantum devices [PDF]
, 2005 Novel hysteretic effects are reported in magneto-transport experiments on lateral quantum devices. The effects are characterized by two vastly different relaxation times (minutes and days).

Subpicotesla Diamond Magnetometry
Physical Review X, 2015 Nitrogen-vacancy (NV) defect centers in diamond are promising solid-state magnetometers. Single centers allow for high-spatial-resolution field imaging but are limited in their magnetic field sensitivity. Using defect-center ensembles, sensitivity can be

Scale-invariant spin dynamics and the quantum limits of field sensing
New Journal of Physics, 2020 We describe quantum limits to field sensing that relate noise, geometry and measurement duration to fundamental constants, with no reference to particle number.

Differential magnetometry: selective magnetometry for in vivo use
, 2023 The implementation of magnetic detection techniques in clinical practice has long lagged behind developments in society as a whole. Whilst techniques like magnetic resonance imaging and (to a lesser extent) MEG/MCG have been succesfully introduced, use of magnetic techniques for diagnostics and treatment has always been limited to well controlled ...

Visible to Infrared Diamond Photonics Enabled by Focused Femtosecond Laser Pulses
Micromachines, 2017 Diamond’s nitrogen-vacancy (NV) centers show great promise in sensing applications and quantum computing due to their long electron spin coherence time and because they can be found, manipulated, and read out optically.
