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 challen

In magnetometry using quantum defects in diamond (NV− centers), we demonstrate forty-fold speedup with sequential Bayesian experiment design as compared with conventional NV- magnetometry using frequency-swept measurements.

We describe a real-time method to obtain normalized differential count rate signals from modulated systems with photon detection at single-photon count rates. The method is demonstrated with a real-time peak-locking and frequency control to track mag

Nuclear spins of phosphorus [P] donor atoms in crystalline silicon are among the most coherent qubits found in nature. For their utilization in scalable quantum computers, distinct donor electron wavefunctions must be controlled and probed through el

E' centers in amorphous silicon dioxide are paramagnetic, highly localized dangling-bond states with long spin-relaxation times. The authors study the E' center for use as a readout probe in force-detected single-spin tunneling force microscopy with

A comprehensive study of a force detected single-spin magnetic resonance measurement concept with atomic spatial resolution is presented. The method is based upon electrostatic force detection of spin-selection rule controlled single-electron tunneli

Separating the influence of hyperfine from spin-orbit interactions in spin-dependent carrier recombination and dissociation processes necessitates magnetic resonance spectroscopy over a wide range of frequencies. We have designed compact and versatil
