Dynamic cantilever magnetometry of individual CoFeB nanotubes [PDF]

, 2016
We investigate single CoFeB nanotubes with hexagonal cross section using dynamic cantilever magnetometry (DCM). We develop both an analytical model based on the Stoner-Wohlfarth approximation and a broadly applicable numerical framework for analyzing DCM

Bounds on distinguishing separated wires using magnetic field measurements

Journal of Physics Communications
Magnetic current imaging (MCI) is useful for non-destructive characterization of microelectronics, including both security analysis and failure analysis, because magnetic fields penetrate the materials that comprise these components to enable through ...

Surface and inter-phase analysis of Composite Materials using Electromagnetic Techniques based on SQUID Sensors

, 2006
In this thesis an electromagnetic characterization and a non-destructive evaluation of new advanced composite materials, Carbon Fiber Reinforced Polymers (CFRP) and Fiber-Glass Aluminium (FGA) laminates, using an eddy-current technique based on HTS dc ...

Imaging with NV ensembles: Beyond magnetometry

, 2023
Vector magnetometry with NV ensembles often overlooks the Hamiltonian Stark term, which contains contributions from both electric and stress fields. Here we show that both the Electric field vector and full stress tensor can also be measured, further ...

Principles and techniques of the quantum diamond microscope

Nanophotonics, 2019
We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the quantum diamond microscope (QDM). The QDM employs a dense layer of fluorescent nitrogen-vacancy (NV) color centers near the surface of a ...

Inferring the magnetic anisotropy of a nanosample through dynamic cantilever magnetometry measurements

, 2020
The magnetic anisotropy of bit-patterned media, such as a mesocrystal, is a key parameter in spintronics. Here, we utilize the high sensitivity of dynamic cantilever magnetometry to investigate the foundation of a mesocrystal, an individual CoFe2O4 ...

Unmanned Aerial Geophysical Remote Sensing: A Systematic Review

Remote Sensing
Geophysical surveys, a means of analyzing the Earth and its environments, have traditionally relied on ground-based methodologies. However, up-to-date approaches encompass remote sensing (RS) techniques, employing both spaceborne and airborne platforms ...

Optimized single-crystal diamond scanning probes for high sensitivity magnetometry

New Journal of Physics, 2018
The negatively-charged nitrogen-vacancy center (NV) in diamond forms a versatile system for quantum sensing applications. Combining the advantageous properties of this atomic-sized defect with scanning probe techniques such as atomic force microscopy ...

Trypillia megasites west of the River Southern Buh: Preliminary results of Bilyi Kamin site investigation in 2018

Journal of Neolithic Archaeology, 2019
In Bilyi Kamin, Ukraine, a Trypillia megasite of the Chechelnyk group west of the River Southern Buh was systematically investigated by high-resolution magnetometry, targeted excavations and radiometric dating. These new data make it possible to discuss

Quantum Kalman filtering and the Heisenberg limit in atomic magnetometry [PDF]

, 2003
The shot-noise detection limit in current high-precision magnetometry [I. Kominis, T. Kornack, J. Allred, and M. Romalis, Nature (London) 422, 596 (2003)] is a manifestation of quantum fluctuations that scale as rootN in an ensemble of N atoms.
