Optical Widefield Nuclear Magnetic Resonance Microscopy
Karl D. Briegel, Nick R. von Grafenstein, Julia C. Draeger +3
Microscopy enables detailed visualization and understanding of minute structures or processes. While cameras have significantly advanced optical, infrared, and electron microscopy,…
A Comprehensive Approach to Characterize Navigation Instruments for Magnetic Guidance in Biological Systems
Peter Blümler, Fabian Raudzus, Friederike Schmid
The non-invasive spatiotemporal control of cellular functions, organization of tissues, and even the behavior of small animals has become paramount for advanced therapies. As magne…
SPECT: A spin-flip loaded magnetic ultracold neutron trap for a determination of the neutron lifetime
J. Auler, M. Engler, K. Franz +13
The confinement of ultracold neutrons (UCNs) in a three dimensional magnetic field gradient trap allows for a measurement of the free neutron lifetime with superior control over sp…
Practical Concepts for Design, Construction and Application of Halbach Magnets in Magnetic Resonance
Peter Blümler, Helmut Soltner
This review is a compilation of relevant concepts in designing Halbach multipoles for magnetic resonance applications. The main focus is on providing practical guidelines to plan,…
Demonstration of diamond nuclear spin gyroscope
Andrey Jarmola, Sean Lourette, Victor M. Acosta +5
We demonstrate operation of a rotation sensor based on the N nuclear spins intrinsic to nitrogen-vacancy (NV) color centers in diamond. The sensor employs optical polarizati…
High homogeneity permanent magnet for diamond magnetometry
Arne Wickenbrock, Huijie Zheng, Georgios Chatzidrosos +3
Halbach magnets are a source of homogeneous magnetic field in an enclosed volume while keeping stray fields at a minimum. Here, we present the design, construction, and characteriz…
Variable single-axis magnetic-field generator using permanent magnets
Oleg Tretiak, Peter Blümler, Lykourgos Bougas
We present a design for producing precisely adjustable and alternating single-axis magnetic fields based on nested Halbach dipole pairs consisting of permanent magnets only. Our de…
Permanent magnet system to guide superparamagnetic particles
Olga Baun, Peter Blümler
A new concept of permanent magnet systems for guiding superparamagnetic particles on arbitrary trajectories is proposed. The basic concept is to use one magnet system with a strong…
Precise Measurement of Magnetic Field Gradients from Free Spin Precession Signals of He and Xe Magnetometers
F. Allmendinger, P. Blümler, M. Doll +12
We report on precise measurements of magnetic field gradients extracted from transverse relaxation rates of precessing spin samples. The experimental approach is based on the free…
Spherical Fused Silica Cells Filled with Pure Helium for NMR-Magnetometry
Andreas Maul, Peter Blümler, Werner Heil +4
High magnetic fields (> 1 T) are measured by NMR magnetometers with un-rivaled precision if the precessing spin sample provides long coherence times. The longest coherence times ar…
Ultrasensitive 3He magnetometer for measurements of high magnetic fields
A. Nikiel, P. Blümler, W. Heil +6
We describe a 3He magnetometer capable to measure high magnetic fields (B > 0.1 Tesla) with a relative accuracy of better than 10^-12. Our approach is based on the measurement of t…
