Physical Review Letters, 1992
A quasimirrorless laser is shown to exhibit large interferences between macroscopic quantum states when submitted to weak external magnetic fields. Such a device is shown to have potentialities as a high signal-to-noise ratio vectorial magnetometer, especially because of its sensitivity to the mean value of the longitudinal magnetic field and its fast ...

Subpicotesla Optomechanical Magnetometry
Physical Review LettersHigh-sensitivity magnetometry has found important applications in fields ranging from basic science studies such as searching for dark matter and exotic particles to more practical tasks in geology, archaeology, navigation, and biomedicine. Currently, the performance of typical high-sensitivity magnetometers is limited by the required stringent ...

A magnetometer is an instrument to measure the magnitude and direction of a magnetic field. The most commonly used magnetometric technique to characterize magnetic materials is vibrating sample magnetometry (VSM). VSMs can measure the magnetic properties of magnetically soft (low coercivity) and hard (high coercivity) materials in many forms: solids ...

SPIE Proceedings, 2008
Innovations may lead to magnetic sensors with superior performance. Examples of this are the chip scale atomic magnetometer, magnetic tunnel junctions with MgO barriers, and a device for minimizing the effect of 1/ f noise, the MEMS flux concentrator.

Compact dynamic cantilever magnetometry
Review of Scientific InstrumentsDynamic cantilever magnetometry (DCM) is a highly sensitive technique for detecting magnetization in individual low-dimensional magnetic materials, superconductors, and magnetotactic bacteria. However, existing instruments use a three-dimensional positioning stage to focus the laser on the cantilever, resulting in a bulky probe head, ∼100 mm in ...

IEEE Transactions on Magnetics, 1981
This article reviews developments in magnetometry since the symposium of the 12th Annual Conference on Magnetism and Magnetic Materials in 1966. No new principles have been discovered since then. However, many variations of force, magnetic induction and indirect techniques have been published which satisfy a variety of different applications. The basic
