Detection of J-Coupling Using Atomic Magnetometer

NIST Inventors
John Kitching
NMR endures as one of the most powerful analytical tools for detecting chemical species and elucidating molecular structure. Zero-to-ultralow-field NMR spectroscopy is a new, potentially portable and cost-effective modality to determine the molecular structure and properties of microfluidic chemical samples.
Schematic of magnetometer/gyroscope shows layers with photodetectors on top and laser at bottom.

Compact Atomic Magnetometer and Gyroscope

NIST Inventors
John Kitching and Elizabeth Donley
Gyroscopes sense rotation. In combination with magnetometers, gyroscopes are used many applications. The NIST invention enables multitasking measurement capabilities and is the first to demonstrate simultaneous measurement of rotation, rotation angle and acceleration with a single source of atoms.
Fiber magnetometer

Chip-Scale Atomic Magnetometer

NIST Inventors
John Kitching and Vladislav Gerginov
Measurement of faint magnetic fields is critical to many applications, including medical diagnostics, but conventional technologies are often large, complex and expensive. NIST’s chip-scale atomic magnetometer is highly compact and readily fabricated using familiar semiconductor techniques.
