Local, mm-scale H magnetic resonance imaging using atomic vapors
Sven Bodenstedt, Morgan W. Mitchell, Michael C. D. Tayler
We demonstrate a practical and sensitive low-field approach to magnetic resonance imaging (MRI) of L-scale samples using an optically pumped magnetometer (OPM). Using a simple s…
Dynamics of hyperpolarized nuclear spins at Zeeman-insensitive points
James Eills, Anushka Singh, Amir-Mahyar Teimoori +3
Avoided crossing (LAC) transitions are central to spin-based precision measurements since they provide strong observability and field-perturbation insensitivity, but while observed…
Cyclicity of interaction frame transformations
Michael C D Tayler, Mohamed Sabba
We identify a cyclic property of rotation sequences involving piecewise displacements about arbitrary axes in three dimensions. Specifically, when transformation to the togglin…
Zero- to Ultralow-field Nuclear Magnetic Resonance
Danila A. Barskiy, John W. Blanchard, Dmitry Budker +5
Zero and ultralow-field nuclear magnetic resonance (ZULF NMR) is an NMR modality where experiments are performed in fields at which spin-spin interactions within molecules and mate…
High-sensitivity multichannel zero-to-ultralow field NMR with atomic magnetometer arrays
Blake Andrews, Matthew Lai, Zhen Wang +4
Despite its versatility and high chemical specificity, conventional NMR spectroscopy is limited in measurement throughput due to the need for high-homogeneity magnetic fields, nece…
Functionalized mm-scale vapor cells for alkali-metal spectroscopy and magnetometry
Harini Raghavan, Michael C. D. Tayler, Kostas Mouloudakis +9
We describe micro-fabricated rubidium vapor cells with integrated temperature-control functionality and demonstrate their suitability for use in miniaturized ultra-sensitive magnet…
Laser-written micro-channel atomic magnetometer
Andrea Zanoni, Kostas Mouloudakis, Michael C. D. Tayler +4
We demonstrate a sensitive optically-pumped magnetometer using rubidium vapor and 0.75 amg of nitrogen buffer gas in a sub-mm-width sensing channel excavated by femtosecond laser w…
Live magnetic observation of parahydrogen hyperpolarization dynamics
James Eills, Morgan W. Mitchell, Irene Marco Rius +1
Hyperpolarized nuclear spins in molecules exhibit high magnetization that is unachievable by classical polarization techniques, making them widely used as sensors in physics, chemi…
Real-time polarimetry of hyperpolarized C nuclear spins using an atomic magnetometer
Kostas Mouloudakis, Sven Bodenstedt, Marc Azagra +3
We introduce a method for non-destructive quantification of nuclear spin polarization, of relevance to hyperpolarized spin tracers widely used in magnetic resonance from spectrosco…
Meridional composite pulses for low-field magnetic resonance
Sven Bodenstedt, Morgan W. Mitchell, Michael C. D. Tayler
We discuss procedures for error-tolerant spin control in environments that permit transient, large-angle reorientation of magnetic bias field. Short sequences of pulsed, non-resona…
Miniature biplanar coils for alkali-metal-vapor magnetometry
Michael C. D. Tayler, Kostas Mouloudakis, Rasmus Zetter +5
Atomic spin sensors offer precision measurements using compact, microfabricated packages, placing them in a competitive position for both market and research applications. Performa…
Decoupling of Spin Decoherence Paths near Zero Magnetic Field
Sven Bodenstedt, Morgan W. Mitchell, Michael C. D. Tayler
We demonstrate a method to quantify and manipulate nuclear spin decoherence mechanisms that are active in zero to ultralow magnetic fields. These include: (i) non-adiabatic switchi…
Fast-field-cycling, ultralow-field nuclear magnetic relaxation dispersion
Sven Bodenstedt, Morgan Mitchell, Michael Tayler
Optically pumped magnetometers (OPMs) based on alkali-atom vapors are ultra-sensitive devices for dc and low-frequency ac magnetic measurements. Here, in combination with fast-fiel…
Instrumentation for nuclear magnetic resonance in zero and ultralow magnetic field
Michael C. D. Tayler, Thomas Theis, Tobias F. Sjolander +5
We review instrumentation for nuclear magnetic resonance (NMR) in zero and ultra-low magnetic field (ZULF, below 0.1 T) where detection is based on a low-cost, non-cryogenic, sp…
