Optical Magnetometer Array for Fetal Magnetocardiography
Optical Magnetometer Array Fetal Magnetocardiography
2012/2/22
We describe an array of spin-exchange relaxation free optical magnetometers designed for detection of fetal magnetocardiography (fMCG) signals. The individual magnetometers are configured with a small...
Detection of a single cobalt microparticle with a microfabricated atomic magnetometer
single cobalt microparticle microfabricated atomic magnetometer Instrumentation and Detectors
2011/7/11
Abstract: We present magnetic detection of a single, 2 {\mu}m diameter cobalt microparticle using an atomic magnetometer based on a microfabricated vapor cell. These results represent an improvement b...

2011/6/23
We present a portable four-channel atomic magnetometer array operating in the spin exchange relaxation-free regime. The magnetometer array has several design
features intended to maximize its suitabi...
Limit on Lorentz and CPT violation of the bound Neutron Using a Free Precession 3He/129Xe co-magnetometer
Lorentz CPT violation of the bound Neutron Free Precession 3He/129Xe co-magnetometer
2010/11/15
We report on the search for Lorentz violating sidereal variations of the frequency difference of colocated spin-species while the Earth and hence the laboratory reference frame rotates with respect to...
