We welcome suggestions of alternative referees. The Stern-Gerlach experiment is a seminal experiment in quantum physics, involving the interaction between a particle with spin and an applied magnetic field gradient. A recent article [Wennerström et al., Phys. Chem. Chem. Phys., 2012, 14, 1677-1684 claimed that a full understanding of the Stern-Gerlach experiment can only be attained if transverse spin relaxation is taken into account, generated by fluctuating magnetic fields originating in the magnetic materials which generate the field gradient. This interpretation is contrary to the standard quantum description of the Stern-Gerlach experiment, which requires no dissipative effects. We present simulations of conventional quantum dynamics in the Stern-Gerlach experiment, using extended Wigner functions to describe the propagation of the quantum state in space and time. No relaxation effects are require...

“…1, left) 3 . In the historical Rabi experiment [1], where the fraction of atoms remaining in the initially prepared state is measured after the action of the rf field for a variable time depending on the molecular velocity, the observed resonance curve is indeed described by Eq. 3, simply replacing the oscillating sin 2 term by its time-averaged value, 1/2.…”

“…In even earlier experiments, Rabi had shown that an oscillating magnetic field could induce transitions between levels associated to the spin state of various nuclei in an applied static magnetic field [1]. This pioneering work was performed on molecular beams, using a selection and detection method of the nuclear spin state similar to that developed in the 1920's by Stern and Gerlach for their demonstration of spin quantification in silver atoms.…”

“…The transposition of Rabi's observation of Nuclear Magnetic Resonance (NMR) in a beam of independent molecules to solid and liquid samples was successfully done independently in 1945 by Purcell and by Bloch. 1 The key feature of both experiments was the observation of the resonance phenomenon through electromagnetic detection at the resonance frequency. At the M.I.T., 2 Purcell, Torrey, and Pound, worked on solid paraffin filling a 1-liter cavity tuned at 30 MHz.…”

Abstract. Two rather similar historical evolutions are evoked, each one originating in fundamental spin studies by physicists, and ending as magnetic resonance imaging (MRI), a set of invaluable tools for clinical diagnosis in the hands of medical doctors. The first one starts with the early work on nuclear magnetic resonance, the founding stone of the usual proton-based MRI, of which the basic principles are described. The second one starts with the optical pumping developments made to study the effects of spin polarization in various fundamental problems. Its unexpected outcome is a unique imaging modality, also based on MRI, for the study of lung physiology and pathologies.

Magnetic Field Mapping

Magnetic field mapping is the production of maps or images of magnetic fields in space. Magnetic field maps are needed for designing and optimizing of magnets used in particle accelerators, spectrometers (mass, nuclear magnetic resonance, and electron paramagnetic resonance), and magnetic resonance imaging systems. Magnetic field maps are also used in geologic exploration where the variations in the magnitude and direction of the earth's magnetic field are indicative of subsurface features and objects. Field mapping relies on various methods of measuring the magnetic field, generally one point at a time. These measurement methods are the main focus of this article. It is curious to note that most measurement methods have remained virtually unchanged for a very long period, but the equipment has been subject to continual development. In this article, only the more commonly used methods are discussed. These methods are complementary and a wide variety of the equipment is readily available from industry. For the many other existing measurement methods, a more complete discussion can be found in two classical bibliographical reviews. Much of the material was presented at the CERN Accelerator School on Measurement and Alignment of Accelerator and Detector Magnets.
