The diurnal flow pattern of field-aligned currents
Journal of Geophysical Research, 1974Gross characteristics of the vector magnetic field perturbations detected by the Triad satellite at 800-km altitude in the auroral oval are analyzed as a function of dipole local time (DLT) under a broad range of magnetic activity. The perturbations are always transverse to the main field and thus result from field-aligned currents.

Field‐aligned currents in the magnetospheric boundary layer
Journal of Geophysical Research: Space Physics, 1980A self‐consistent magnetopause‐boundary layer model is constructed which contains two current layers, one for the magnetopause and one for the magnetosphere‐boundary layer transition region. Field‐aligned sheet currents in the boundary layer are generated by the plasma flow along the boundary layer.

Finite geometry effects of field‐aligned currents
Journal of Geophysical Research: Space Physics, 1992Traditionally, field‐aligned current densities calculated from gradients in the perturbation magnetic field measured from low‐altitude spacecraft have been based on the assumption that the current regions are infinite in length. However, many measurements clearly indicate that this assumption is invalid.

Dynamo-electric field-aligned currents in the plasmasphere
Journal of Atmospheric and Terrestrial Physics, 1978Abstract The dynamo-theory has been used to interpret antisymmetric Sq-variations. The following results have been found analytically: 1. The antisymmetric electric field is important only for driving field-aligned coupling currents between both hemispheres. 2.
