Unidirectional transmission of electrons in a magnetic field gradient [PDF]
Physica E: Low-dimensional Systems and Nanostructures, 2004 The work presents an experimental demonstration of time-reversal asymmetry of electron states propagating along boundary separating areas with opposite magnetic fields. For this purpose we have fabricated a hybrid ferromagnet-semiconductor device in form of a Hall cross with two ferromagnets deposited on top.

Manipulation of skyrmion motion by magnetic field gradients [PDF]
Nature Communications, 2018 AbstractMagnetic skyrmions are particle-like, topologically protected magnetisation entities that are promising candidates as information carriers in racetrack memory. The transport of skyrmions in a shift-register-like fashion is crucial for their embodiment in practical devices.

Magnetic Field Gradients and Their Uses in the Study of the Earth's Magnetic Field.
Journal of geomagnetism and geoelectricity, 1991 Magnetic field gradients are discussed from the standpoint of their usefulness in modeling crustal magnetizations. The fact that gradients enhance shorter wavelength features helps reduce both the core signal and the signal from external fields in comparison with the crustal signal.

Rigorous evaluation of the edge-focusing wiggler based on the magnetic field measurement
Physical Review Special Topics. Accelerators and Beams, 2009 The edge-focusing (EF) wiggler, which produces the strong field gradient for transverse focusing incorporated with the normal wiggler field, has been fabricated to evaluate its performance rigorously with the magnetic field measurement.
